Phase 1 complete: 5 new crates, event bus, scheduler, state, resources

New crates (5):
- rpa-config: configuration loading + Nickel bridge + validators (6 tests)
- rpa-events: async pub/sub event bus with pre/post lifecycle hooks (5 tests)
- rpa-resources: semaphore-based resource pooling + ResourceManager (5 tests)
- rpa-scheduler: cron expression parser + scheduled task execution (6 tests)
- rpa-state: persistence layer with JsonFileBackend + snapshots (11 tests)

Integration:
- rpa-fs-workflow now delegates config loading to rpa-config::ConfigLoader
- Workspace expanded from 3 to 8 crates (48 total tests, zero warnings)

Documentation:
- ROADMAP: Phase 1 COMPLETE, Phases 6-10 added (Enterprise, Distributed,
  AI-Native, Marketplace, Autonomous Operations)
- README: Phase 2 next, 8-crate description
- TOPOLOGY: all new crates at 100%, overall 55%
- STATE: completion 55%, next actions = Phase 2
- META: ADR-009 (event bus), ADR-010 (resource pooling)
