Add MCP investigation tools and fix native module packaging

Add 5 new MCP tools (triage, investigate-crashes, investigate-component,
compare-baseline, investigate-timerange) with corresponding API endpoints.
Fix native module packaging by adding asarUnpack for better-sqlite3,
node-pty, and serialport so packaged apps load correctly on all platforms.
