Erik M Jacobs 3ea180c1ef refactor(worker): Remove file-based locking and improve Windows stability
This commit simplifies worker startup coordination and addresses Windows-specific issues:

**Lock Removal**:
- Removed entire file-based locking system (~100 lines)
- Replaced with health-check-first approach
- Port binding provides natural mutual exclusion - multiple spawns fail cleanly

**Windows Stability**:
- Removed all AbortSignal.timeout() calls to reduce Bun libuv assertion errors
- Added 500ms shutdown delays on Windows to prevent zombie ports
- Worker service has its own timeouts, so client-side timeouts are redundant

**Package.json Updates**:
- Updated worker scripts to use worker-service.cjs directly
- Removed references to deleted worker-cli.js and worker-wrapper.cjs

**Key Changes**:
- src/services/worker-service.ts: Lock removal, shutdown delays, simplified start logic
- src/hooks/*.ts: Removed AbortSignal.timeout from all HTTP requests
- src/shared/worker-utils.ts: Removed AbortSignal.timeout from health checks
- package.json: Updated worker:* scripts

Resolves startup hangs, reduces assertion errors, and prevents zombie port issues.
