fix: resolve all ruff lint and format errors across codebase (#7058)

- Auto-fixed 70 lint errors (import sorting, aliased errors, datetime.UTC)
- Fixed 85 remaining errors manually:
  - E501: wrapped long lines in queen_profiles, catalog, routes_credentials
  - F821: added missing TYPE_CHECKING imports for AgentHost, ToolRegistry,
    HookContext, HookResult; added runtime imports where needed
  - F811: removed duplicate method definitions in queen_lifecycle_tools
  - F841/B007: removed unused variables in discovery.py
  - W291: removed trailing whitespace in queen nodes
  - E402: moved import to top of queen_memory_v2.py
  - Fixed AgentRuntime -> AgentHost in example template type annotations
- Reformatted 343 files with ruff format
