feat: add database migration v9→v10 for Hermes support (Phase 2)

- Bump SCHEMA_VERSION from 9 to 10
- Add enabled_hermes column to mcp_servers and skills tables
- Add migrate_v9_to_v10 with table_exists guard for skills (may not
  exist in databases migrated from very old versions)
- Update dao/mcp.rs to fully read/write enabled_hermes in all queries
- Update dao/skills.rs: don't SELECT enabled_hermes (Hermes doesn't
  support Skills yet), keep column indices clean
