Split the monolithic context.py (117 lines) into five purpose-specific
modules following single-responsibility principle:
- config.py: Server-level constants (DATA_DIR, SESSIONS_DIR, PORT,
STALE_EVENT_AGE, _state_lock)
- agents.py: Agent-specific paths and caches (CLAUDE_PROJECTS_DIR,
CODEX_SESSIONS_DIR, discovery caches)
- auth.py: Authentication token generation/validation for spawn endpoint
- spawn_config.py: Spawn feature configuration (PENDING_SPAWNS_DIR,
rate limiting, projects watcher thread)
- zellij.py: Zellij binary resolution and session management constants
This refactoring improves:
- Code navigation: Find relevant constants by domain, not alphabetically
- Testing: Each module can be tested in isolation
- Import clarity: Mixins import only what they need
- Future maintenance: Changes to one domain don't risk breaking others
All mixins updated to import from new module locations. Tests updated
to use new import paths.
Includes PROPOSED_CODE_FILE_REORGANIZATION_PLAN.md documenting the
rationale and mapping from old to new locations.

Position the spawn modal directly under the 'New Agent' button without a
blur overlay. Uses click-outside dismissal and absolute positioning.
Reduces visual disruption for quick agent spawning.
- Add empty-state message in SpawnModal when no projects found
- Spawn button stays disabled when projects list is empty
- Server already handled OSError/missing dir gracefully (returns [])
- Add tests: missing directory, only-hidden-dirs, empty API responses
Closes: bd-3c7
