feat: add micro build and micro deploy commands

micro build:
  - Generates Dockerfiles for services (if not present)
  - Builds container images for all services in micro.mu
  - Supports --tag, --registry, --push flags
  - --compose flag generates docker-compose.yml

micro deploy:
  - Default: deploys with docker-compose
  - --ssh user@host: deploys via SSH (rsync + build on remote)
  - --build: rebuild images before deploying

Complete workflow:
  micro run          # Develop locally
  micro build        # Build images
  micro deploy       # Deploy

Or for simple SSH deploys:
  micro deploy --ssh user@host

-Go Micro is a framework for microservice development.
+Go Micro is a framework for distributed systems development.
+
+**[📖 Documentation](https://go-micro.dev/docs/)** | [Sponsor the project](https://github.com/sponsors/micro)
 
 ## Overview
 
-Go Micro provides the core requirements for distributed systems development including RPC and Event driven communication. 
-The **micro** philosophy is sane defaults with a pluggable architecture. We provide defaults to get you started quickly 
-but everything can be easily swapped out.

+Go Micro provides the core requirements for distributed systems development including RPC and Event driven communication.
+The Go Micro philosophy is sane defaults with a pluggable architecture. We provide defaults to get you started quickly
+but everything can be easily swapped out.
 
 ## Features
 
 Go Micro abstracts away the details of distributed systems. Here are the main features.
 
-- **Service Discovery** - Automatic service registration and name resolution. Service discovery is at the core of micro service 
-development. When service A needs to speak to service B it needs the location of that service. The default discovery mechanism is 
-multicast DNS (mdns), a zeroconf system.
+- **Authentication** - Auth is built in as a first class citizen. Authentication and authorization enable secure
+  zero trust networking by providing every service an identity and certificates. This additionally includes rule
+  based access control.
 
-- **Load Balancing** - Client side load balancing built on service discovery. Once we have the addresses of any number of instances 
-of a service we now need a way to decide which node to route to. We use random hashed load balancing to provide even distribution 
-across the services and retry a different node if there's a problem. 
+- **Dynamic Config** - Load and hot reload dynamic config from anywhere. The config interface provides a way to load application
+  level config from any source such as env vars, file, etcd. You can merge the sources and even define fallbacks.
 
-- **Message Encoding** - Dynamic message encoding based on content-type. The client and server will use codecs along with content-type 
-to seamlessly encode and decode Go types for you. Any variety of messages could be encoded and sent from different clients. The client 
-and server handle this by default. This includes protobuf and json by default.
+- **Data Storage** - A simple data store interface to read, write and delete records. It includes support for many storage backends
+in the plugins repo. State and persistence becomes a core requirement beyond prototyping and Micro looks to build that into the framework.
 
-- **Request/Response** - RPC based request/response with support for bidirectional streaming. We provide an abstraction for synchronous 
-communication. A request made to a service will be automatically resolved, load balanced, dialled and streamed. The default 
-transport is [gRPC](https://grpc.io/).
+- **Service Discovery** - Automatic service registration and name resolution. Service discovery is at the core of micro service
+  development. When service A needs to speak to service B it needs the location of that service. The default discovery mechanism is
+  multicast DNS (mdns), a zeroconf system.
 
-- **Async Messaging** - PubSub is built in as a first class citizen for asynchronous communication and event driven architectures. 
-Event notifications are a core pattern in micro service development. The default messaging system is an embedded [NATS](https://nats.io/) 
-server.
+- **Load Balancing** - Client side load balancing built on service discovery. Once we have the addresses of any number of instances
+  of a service we now need a way to decide which node to route to. We use random hashed load balancing to provide even distribution
+  across the services and retry a different node if there's a problem.
 
-- **Pluggable Interfaces** - Go Micro makes use of Go interfaces for each distributed system abstraction. Because of this these interfaces 
-are pluggable and allows Go Micro to be runtime agnostic. You can plugin any underlying technology. Find plugins in 
-[github.com/micro/go-plugins](https://github.com/micro/go-plugins).
+- **Message Encoding** - Dynamic message encoding based on content-type. The client and server will use codecs along with content-type
+  to seamlessly encode and decode Go types for you. Any variety of messages could be encoded and sent from different clients. The client
+  and server handle this by default. This includes protobuf and json by default.
+
+- **RPC Client/Server** - RPC based request/response with support for bidirectional streaming. We provide an abstraction for synchronous
+  communication. A request made to a service will be automatically resolved, load balanced, dialled and streamed.
+
+- **Async Messaging** - PubSub is built in as a first class citizen for asynchronous communication and event driven architectures.
+  Event notifications are a core pattern in micro service development. The default messaging system is a HTTP event message broker.
+
+- **Pluggable Interfaces** - Go Micro makes use of Go interfaces for each distributed system abstraction. Because of this these interfaces
+  are pluggable and allows Go Micro to be runtime agnostic. You can plugin any underlying technology.
 
 ## Getting Started
 
-See the [docs](https://micro.mu/docs/framework.html) for detailed information on the architecture, installation and use of go-micro.
+To make use of Go Micro 
 
+```bash
+go get go-micro.dev/v5@latest
+```
+
+Create a service and register a handler
+
+```go
+package main
+
+import (
+        "go-micro.dev/v5"
+)
+
+type Request struct {
+        Name string `json:"name"`
+}
+
+type Response struct {
+        Message string `json:"message"`
+}
+
+type Say struct{}
+
+func (h *Say) Hello(ctx context.Context, req *Request, rsp *Response) error {
+        rsp.Message = "Hello " + req.Name
+        return nil
+}
+
+func main() {
+        // create the service
+        service := micro.New("helloworld")
+
+        // register handler
+        service.Handle(new(Say))
+
+        // run the service
+        service.Run()
+}
+```
+
+Set a fixed address
+
+```go
+service := micro.NewService(
+    micro.Name("helloworld"),
+    micro.Address(":8080"),
+)
+```
+
+Call it via curl
+
+```bash
+curl -XPOST \
+     -H 'Content-Type: application/json' \
+     -H 'Micro-Endpoint: Say.Hello' \
+     -d '{"name": "alice"}' \
+      http://localhost:8080
+```
+
+## Experimental
+
+There's a new `genai` package for generative AI capabilities.
+
+## Protobuf
+
+Install the code generator and see usage in the docs:
+
+```bash
+go install go-micro.dev/v5/cmd/protoc-gen-micro@latest
+```
+
+Docs: [`internal/website/docs/getting-started.md`](internal/website/docs/getting-started.md)
+
+## Command Line
+
+Install the CLI:
+
+```
+go install go-micro.dev/v5/cmd/micro@latest
+```
+
+### Quick Start
+
+```bash
+micro new helloworld   # Create a new service
+cd helloworld
+micro run              # Run with API gateway
+```
+
+Then open http://localhost:8080 to see your service and call it from the browser.
+
+### micro run
+
+`micro run` starts your services with:
+- **API Gateway** - HTTP to RPC proxy at `/api/{service}/{method}`
+- **Web Dashboard** - Browse and call services at `/`
+- **Health Checks** - Aggregated health at `/health`
+- **Hot Reload** - Auto-rebuild on file changes
+
+```bash
+micro run                    # Gateway on :8080
+micro run --address :3000    # Custom gateway port
+micro run --no-gateway       # Services only
+micro run --env production   # Use production environment
+```
+
+### Configuration
+
+For multi-service projects, create a `micro.mu` file:
+
+```
+service users
+    path ./users
+    port 8081
+
+service posts
+    path ./posts
+    port 8082
+    depends users
+
+env development
+    DATABASE_URL sqlite://./dev.db
+```
+
+The gateway runs on :8080 by default, so services should use other ports.
+
+### Deployment
+
+```bash
+micro build              # Build container images
+micro build --compose    # Generate docker-compose.yml
+micro deploy             # Deploy with docker-compose
+micro deploy --ssh user@host  # Deploy via SSH
+```
+
+See [cmd/micro/README.md](cmd/micro/README.md) for full CLI documentation.

-Go Micro是基于Golang的微服务开发框架。
-
-## 概览
-
-Go Micro提供分布式系统开发的核心库，包含RPC与事件驱动的通信机制。
-
-**micro**的设计哲学是可插拔的架构理念，她提供可快速构建系统的组件，并且可以根据自身的需求剥离默认实现并自行定制。
-
-<img src="https://micro.mu/docs/images/go-micro.svg" />
-
-所有插件可在仓库[github.com/micro/go-plugins](https://github.com/micro/go-plugins)中找到。
-
-可以订阅我们的[Twitter](https://twitter.com/microhq)或者加入[Slack](http://slack.micro.mu/)论坛。
-
-## 特性
-
-Go Micro把分布式系统的各种细节抽象出来。下面是它的主要特性。
-
-- **服务发现（Service Discovery）** - 自动服务注册与名称解析。服务发现是微服务开发中的核心。当服务A要与服务B协作时，它得知道B在哪里。默认的服务发现系统是Consul，而multicast DNS (mdns，组播)机制作为本地解决方案，或者零依赖的P2P网络中的SWIM协议（gossip）。 
-
-- **负载均衡（Load Balancing）** - 在服务发现之上构建了负载均衡机制。当我们得到一个服务的任意多个的实例节点时，我们要一个机制去决定要路由到哪一个节点。我们使用随机处理过的哈希负载均衡机制来保证对服务请求颁发的均匀分布，并且在发生问题时进行重试。
-
-- **消息编码（Message Encoding）** - 支持基于内容类型（content-type）动态编码消息。客户端和服务端会一起使用content-type的格式来对Go进行无缝编/解码。各种各样的消息被编码会发送到不同的客户端，客户端服服务端默认会处理这些消息。content-type默认包含proto-rpc和json-rpc。
-
-- **Request/Response** - RPC通信基于支持双向流的请求/响应方式，我们提供有抽象的同步通信机制。请求发送到服务时，会自动解析、负载均衡、拨号、转成字节流。默认的传输协议是http/1.1，而tls下使用http2协议。
-
-- **异步消息（Async Messaging）** - 发布订阅（PubSub）头等功能内置在异步通信与事件驱动架构中。事件通知在微服务开发中处于核心位置。默认的消息传送使用点到点http/1.1，激活tls时则使用http2。
-
-- **可插拔接口（Pluggable Interfaces）** - Go Micro为每个分布式系统抽象出接口。因此，Go Micro的接口都是可插拔的，允许其在运行时不可知的情况下仍可支持。所以只要实现接口，可以在内部使用任何的技术。更多插件请参考：[github.com/micro/go-plugins](https://github.com/micro/go-plugins)。

-# Discord input for micro-bot
-[Discord](https://discordapp.com) support for micro bot based on [discordgo](github.com/bwmarrin/discordgo).
-
-This was originally written by Aleksandr Tihomirov (@zet4) and can be found at https://github.com/zet4/micro-misc/.
-
-## Options
-### discord_token
-
-You have to supply an application token via `--discord_token`.
-
-Head over to Discord's [developer introduction](https://discordapp.com/developers/docs/intro)
-to learn how to create applications and how the API works.
-
-### discord_prefix
-
-Set a command prefix with `--discord_prefix`. The default prefix is `Micro `.
-You can mention the bot or use the prefix to run a command.
-
-### discord_whitelist
-
-Pass a list of comma-separated user IDs with `--discord_whitelist`. Only allow
-these users to use the bot.
