Drop the Maintainability Guardrails docs section and remove the fan-in/runtime-cycle guardrail scripts from local and CI workflows so contributor guidance matches current validation lanes.
Split config defaults, option metadata, runtime-option registry, and template sections into domain modules while preserving the composed public API in definitions.ts. This keeps ConfigService behavior stable and makes future config extensions easier to add with focused regression coverage.
Introduce runtime domain barrel exports and registry composition support, and document/check main runtime fan-in workflow with related backlog planning artifacts.
Detach --background launches from terminals with quieter runtime output, make wrapper/plugin overlay start explicit, and allow trailing commas in JSONC configs for safer hot-reload edits. Includes pending Anki/docs/backlog updates in this unreleased batch.
- Document src/main/ composition modules (startup, app-lifecycle, state, etc.)
- Add new services to service layer list (app-ready, mpv-transport, etc.)
- Update flow diagrams to show new composition module structure
- Update contributor notes in development.md
