# HOMECORE-PLUGINS — WASM integration plugin system.
# Implements ADR-128 (HOMECORE-PLUGINS), P1 scaffold:
#   - PluginManifest (serde-deserialised, superset of HA manifest.json)
#   - HomeCorePlugin async trait + PluginId + PluginError
#   - PluginRuntime trait + InProcessRuntime (native Rust, first-party plugins)
#   - PluginRegistry (load / unload / list)
#
# P2 will add the `wasmtime` feature (gated below, default-off) for the real
# Wasmtime JIT sandbox. wasm3 interpretation mode lands behind `--features wasm3`
# in P3 for constrained-hardware targets.
