## Description

Unity Profiler session control, counter reads, memory snapshots, and Frame Debugger.

SESSION:
- profiler_start: Enable profiler, optionally record to .raw file (log_file, enable_callstacks)
- profiler_stop: Disable profiler, stop recording
- profiler_status: Get enabled state, active areas, recording path
- profiler_set_areas: Toggle ProfilerAreas on/off (areas dict)

COUNTERS:
- get_frame_timing: FrameTimingManager data (12 fields, synchronous)
- get_counters: Generic counter read by category + optional counter names (async, 1-frame wait)
- get_object_memory: Memory size of a specific object by path

MEMORY SNAPSHOT (requires com.unity.memoryprofiler):
- memory_take_snapshot: Capture memory snapshot to file
- memory_list_snapshots: List available .snap files
- memory_compare_snapshots: Compare two snapshot files

FRAME DEBUGGER:
- frame_debugger_enable: Turn on Frame Debugger, report event count
- frame_debugger_disable: Turn off Frame Debugger
- frame_debugger_get_events: Get draw call events (paged, best-effort via reflection)

## Parameters

| Name | Type | Required | Description |
|------|------|----------|-------------|
| `action` | `str` | yes | The profiler action to perform. |
| `category` | `str \| None` | — | Profiler category name for get_counters (e.g. Render, Scripts, Memory, Physics). |
| `counters` | `list[str] \| None` | — | Specific counter names for get_counters. Omit to read all in category. |
| `object_path` | `str \| None` | — | Scene hierarchy or asset path for get_object_memory. |
| `log_file` | `str \| None` | — | Path to .raw file for profiler_start recording. |
| `enable_callstacks` | `bool \| None` | — | Enable allocation callstacks for profiler_start. |
| `areas` | `dict[str, bool] \| None` | — | Dict of area name to bool for profiler_set_areas. |
| `snapshot_path` | `str \| None` | — | Output path for memory_take_snapshot. |
| `search_path` | `str \| None` | — | Search directory for memory_list_snapshots. |
| `snapshot_a` | `str \| None` | — | First snapshot path for memory_compare_snapshots. |
| `snapshot_b` | `str \| None` | — | Second snapshot path for memory_compare_snapshots. |
| `page_size` | `int \| None` | — | Page size for frame_debugger_get_events (default 50). |
| `cursor` | `int \| None` | — | Cursor offset for frame_debugger_get_events. |

## Returns

A `dict` containing the Unity response. The exact shape depends on the action.
