v0.2.0

Added

• Transform tools: set_transform, duplicate_object, reparent_object
• Profiler tools: profiler_start, profiler_stop, profiler_clear, profiler_get_samples using Unity.Profiling.ProfilerRecorder
• profiler_benchmark: fires a named ProfilerMarker with real CPU work to produce measurable timing samples (use with profiler_start)
• help tool: returns full description and argument details for any command on demand
• screenshot now returns the image inline (base64 PNG) with optional max_size downscale
• execute_script: compile and run C# code snippets in the Editor
• IAgentCommand.Core property: command classes declare themselves as core with bool Core => true
• Go integration tests for profiler commands and execute_script, including a live data-capture test that fires a ProfilerMarker and verifies sampleCount > 0

Changed

• play_mode (single command with action parameter) replaced by play_enter and play_exit (no arguments each)
• run_tests (single command with mode parameter) replaced by run_editor_tests and run_playmode_tests
• commands renamed to list_commands
• console_logs simplified: limit and type filter arguments removed; always returns all buffered logs
• MCP tools/list context cost reduced by 31% (from ~3,000 to ~2,063 tokens) by moving argument descriptions behind the help tool
• serve.go now loads core tools dynamically from Unity at startup via list_commands instead of a hardcoded allowlist. No Go recompile needed when adding new Unity commands.
• agent_schema.json removed; no offline schema cache needed.
• Dropped profiler_set_deep and profiler_get_frame (required internal Unity APIs with no public equivalent)
• Removed --schema CLI flag from dffrnt-agent
