Bohdan Triapitsyn 2031e3b4a8 Decouple bundled UI from runtime API and add remote instance tooling (#1228)
Add a packaged-client runtime boundary so the shared UI can talk to local,
desktop, remote, and VS Code runtimes through the right transport instead of
assuming one same-origin web server.

Centralize OpenChamber-owned API access behind RuntimeAPIs, runtimeFetch, and
runtime URL helpers, while keeping official OpenCode traffic on the SDK path.
Support runtime switching, remote host selection, desktop client credentials,
and headless connection links for pairing packaged clients with remote
OpenChamber servers.

Harden the new auth model by moving long-lived client tokens out of browser
URLs, introducing short-lived scoped URL tokens for browser-owned transports,
restricting URL-token access to explicit readable/realtime routes, and making
client-token management session-scoped or self-scoped as appropriate.

Update browser-owned assets and preview proxy flows to work with the split
runtime model, including authenticated project icons, preview token propagation,
CSP-safe preview bridge injection, and preview proxy auth that survives
short-lived URL-token expiry.

Tighten Electron security boundaries for packaged clients by gating privileged
preload state to trusted origins and requiring explicit confirmation before
connect deep-links import or switch remote runtimes.

Also refresh agent guidance and project skills so future runtime/API, auth,
preview, UI, CLI, settings, locale, and drag-to-reorder work follows the new
architecture.

Adding Themes

Custom Themes (User)

Drop a JSON file into ~/.config/openchamber/themes/. No rebuild needed.

  1. Create theme file (e.g., my-theme.json)
  2. In app: Settings → Theme → Reload themes
  3. Select from dropdown

See docs/CUSTOM_THEMES.md for full format reference.

Built-in Themes (Development)

1. Create JSON Files

Add to packages/ui/src/lib/theme/themes/:

  • <id>-light.json
  • <id>-dark.json

Use existing themes (e.g., flexoki-dark.json) as reference for the full structure.

2. Register in presets.ts

import mytheme_light_Raw from './mytheme-light.json';
import mytheme_dark_Raw from './mytheme-dark.json';

export const presetThemes: Theme[] = [
  // ... existing themes
  mytheme_light_Raw as Theme,
  mytheme_dark_Raw as Theme,
];

3. Validate

bun run type-check && bun run lint && bun run build
