feat(phase3): add remote Claude spawner and project registry

Phase 3 adds the ability to spawn Claude Code instances remotely from Telegram in registered projects.

New Features:
- Project registry system (~/.innervoice/projects.json)
- Remote Claude spawner with process management
- Auto-spawn capability for projects
- Full CRUD operations for projects via Telegram

Telegram Bot Commands:
- /projects - List all registered projects
- /register ProjectName /path [--auto-spawn]
- /unregister ProjectName
- /spawn ProjectName [initial prompt]
- /spawned - List running spawned processes
- /kill ProjectName

API Endpoints:
- GET /projects - List registered projects
- POST /projects/register - Register new project
- DELETE /projects/:name - Unregister project
- GET /projects/:name - Get project details
- POST /spawn - Spawn Claude in project
- POST /kill/:projectName - Kill spawned process
- GET /spawned - List all spawned processes
- GET /spawned/:projectName - Check if project running

Files Added:
- src/project-registry.ts - Project registry management
- src/claude-spawner.ts - Claude process spawning

Files Modified:
- src/index.ts - Added spawner integration, bot commands, API endpoints
