[codex] Migrate ritual UI source workflow

[Evander764]

What changed

• Migrated the Timetable.OS ritual/UI work back into source instead of patching packaged app.asar.
• Added source-owned entry/exit ritual HTML generation, multiple ritual modes, configurable ritual copy, and local Web Audio ambience.
• Reworked the visual system around black/white/gray ledger styling with orange action accents, updated shell controls, buttons, toggles, sidebar, title bar, cards, and desktop widgets.
• Added source scripts for user-data archiving, clean builds, and local deployment, plus handoff docs for the source-first workflow.
• Restored/kept user data compatibility in reducers without committing private app-data.json.

Why

The app had been iterated through packaged output during emergency fixes. This moves the work back to the maintainable source tree so future builds do not erase UI, ritual, data compatibility, or desktop widget fixes.

Validation

• npm.cmd run typecheck
• npm.cmd run lint
• npm.cmd test
• npm.cmd run build
• node --check out/main/index.js
• node --check out/renderer/assets/index-*.js

Notes

This PR intentionally does not include user data, app.asar, unpacked runtime folders, temporary extraction folders, out, or release artifacts.
