Max Litruv Boonzaayer e058165830 feat: upgrade toolchain and soften sync recovery after network blips

Bump Vite 8, matrix-js-sdk, and related deps; fix immer/vanilla-extract imports for new majors. Replace blocking sync error dialog with background recovery on wake/offline, and disable Vite auto-open in dev. Add feature handoff documentation index.

Developer tools — handoff

Summary

Power-user tools for debugging Matrix state: view/edit account data, send custom room events, and inspect raw JSON. Available in user settings and room/space common-settings.

User-facing behavior

Settings → Developer tools: account data viewer
Room settings → Developer tools: send state events, room account data
Raw JSON editors with validation warnings

Architecture

settings/developer-tools/
  DevelopTools.tsx, AccountData.tsx
common-settings/developer-tools/
  DevelopTools.tsx, StateEventEditor.tsx, SendRoomEvent.tsx

Key files

Path	Role
`cinny/src/app/features/settings/developer-tools/DevelopTools.tsx`	User-level dev tools
`cinny/src/app/features/settings/developer-tools/AccountData.tsx`	Account data viewer
`cinny/src/app/features/common-settings/developer-tools/DevelopTools.tsx`	Room dev tools entry
`cinny/src/app/features/common-settings/developer-tools/StateEventEditor.tsx`	Edit state events
`cinny/src/app/features/common-settings/developer-tools/SendRoomEvent.tsx`	Send events

Data model

Direct read/write to Matrix account data and state events — production danger.

Dependencies

matrix-js-sdk low-level APIs

Integration points

user-settings: developer tab
common-settings: per-room tools

Testing

Manual

View account data keys on staging account.
Send harmless custom state event in test room.
Verify permission denied without power level.

Automated

None

Known issues & gotchas

No guard rails — can break rooms with bad state events
Should be hidden or disabled in production builds for normal users (currently settings-gated only)
Typo DevelopTools vs DeveloperTools in filenames

Future work

Feature flag via client config
Event diff viewer
