Phase 4: Atomic operations and stress testing (bd-114, bd-110)

Completes daemon architecture implementation:

Features:
- Batch/transaction API (OpBatch) for multi-step atomic operations
- Request timeout and cancellation support (30s default, configurable)
- Comprehensive stress tests (4-10 concurrent agents, 800-1000 ops)
- Performance benchmarks (daemon 2x faster than direct mode)

Results:
- Zero ID collisions across 1000+ concurrent creates
- All acceptance criteria validated for bd-110
- Create: 2.4ms (daemon) vs 4.7ms (direct)
- Update/List: similar 2x improvement

Tests Added:
- TestStressConcurrentAgents (8 agents, 800 creates)
- TestStressBatchOperations (4 agents, 400 batch ops)
- TestStressMixedOperations (6 agents, mixed read/write)
- TestStressNoUniqueConstraintViolations (10 agents, 1000 creates)
- BenchmarkDaemonCreate/Update/List/Latency
- Fixed flaky TestConcurrentRequests (shared client issue)

Files:
- internal/rpc/protocol.go - Added OpBatch, BatchArgs, BatchResponse
- internal/rpc/server.go - Implemented handleBatch with stop-on-failure
- internal/rpc/client.go - Added SetTimeout and Batch methods
- internal/rpc/stress_test.go - All stress tests
- internal/rpc/bench_test.go - Performance benchmarks
- DAEMON_STRESS_TEST.md - Complete documentation

Closes bd-114, bd-110

Implement bd daemon command with production-ready improvements

- Add bd daemon command for background git sync (bd-273)
- Implement PID file management with atomic creation (O_EXCL)
- Add session detachment (Setsid) to survive terminal closure
- Implement graceful shutdown with SIGTERM/SIGINT/SIGHUP handling
- Add context cancellation and per-sync timeouts (2min)
- Use secure file permissions (0600 for PID/log, 0700 for .beads)
- Add startup confirmation before reporting success
- Implement interval validation and comprehensive error handling
- Add full test coverage for daemon lifecycle
- Update README.md with daemon documentation

All oracle review recommendations implemented.
