Release v5.0.2: Worker health check and async startup improvements

Fixes:
- Fixed worker startup reliability with async health checks
- Added proper error handling to PM2 process spawning
- Worker now verifies health before proceeding with hook operations
- Improved handling of PM2 failures when not yet installed

Technical changes:
- Added isWorkerHealthy() and waitForWorkerHealth() functions to src/shared/worker-utils.ts
- Changed ensureWorkerRunning() from synchronous to async with proper await
- All hooks now await ensureWorkerRunning for reliable worker communication
- Rebuilt all plugin executables with version 5.0.2
- Updated version to 5.0.2 in all metadata files

Root cause: ensureWorkerRunning was synchronous and didn't verify worker was actually responsive before proceeding, causing race conditions and startup failures.
