Pluggable AI providers, relay credit system, picker UX overhaul

Captures roughly forty version bumps (v0.2.6 → v0.2.47) of work that
accumulated without commits.

- Pluggable provider system under server/providers/: gemini, anthropic,
  openai, openai-compatible, ollama, whisper-compatible, relay. Mix and
  match transcription + analysis per request via the picker UI.
- Relay backend integration. Hardcoded relay URL in server/relay-default.js
  (operator-controlled at build time, not user-configurable). New
  /api/relay/{status,policy} endpoints proxy to the relay; balance pings
  populate a cached credit display.
- Per-install identity in server/install-id.js for relay credit accounting.
  Sent to the relay as X-Recap-Install-Id; persists across upgrades, lost
  on a full uninstall + reinstall. Not surfaced in the UI.
- Admin login gate (server/admin-auth.js + setAdminPassword action). Scrypt
  password hash + HMAC-signed session cookie.
- Entitlement scheme rename: pro / max (each paired with subscriptions and
  relay_pro / relay_max), replacing the misleading "core" entitlement
  that conflicted with the user-facing "Core" tier name.
- Activation screen: dynamic credit count pulled from /api/relay/policy,
  "Skip — use free mode" button, accurate paid-feature list.
- Top toolbar: inline credit-balance pill (or "BYO configured" fallback),
  Upgrade + "I have a key" buttons.
- Picker UI: per-provider sections with Save/Test/Delete buttons, sections
  collapsible by chevron, default-collapsed unless currently selected,
  "Use comped credits (reset to relay)" link when the user has strayed,
  green hint under inputs whose values are server-configured.
- Activity log: chevron-collapsible groups per video, refresh-survival via
  localStorage + a 500-entry server-side buffer, explicit Clear button.
- YouTube captions fast-path with user toggle (skips audio download + AI
  transcription when captions are available — uncheck for speaker labels).
- Cancel button: AbortController plumbed through every provider SDK call;
  retryAPI short-circuits on AbortError; cancellation events surface in
  the activity log instead of silent retries.
- Long-video analysis: auto-coalesce transcript entries before building the
  analysis prompt so local-model context windows (32k-ish) don't overflow.
  Original entries preserved for transcript display via an index map; the
  analyzer sees a coarser view but click-to-seek timestamps stay precise.
- StartOS action grouping (Setup / AI Providers) so the actions list is
  navigable.
- Manifest description rewritten to reflect multi-provider support and
  free-tier relay credits.
- Smaller fixes: summarize-button enablement no longer requires a Gemini
  key when other providers are configured; analysis fallback chain handles
  context-length and 503 capacity errors; single-segment expansion for
  providers that don't return per-segment timestamps (Parakeet et al.);
  many other UX polish items.

Much faster, much cheaper. Falls back to AI transcription if captions are missing or unusable. Richer transcription prompt: when we do transcribe, Recap now feeds Gemini the channel name, video description, and YouTube chapter markers — dramatically improving speaker name extraction so transcripts say "Dax:" and "Kristen:" instead of "Host:" and "Guest:". Other 0.2.10 changes: Gemini 2.5 Flash added as a transcription fallback when Gemini 3 Flash gets overloaded; new Test button on each provider in Settings (sends a 3-word ping to confirm your API key works); Ollama and OpenAI-Compatible providers now have a Models field in Settings — type comma-separated model names there and they appear as dropdown options in the picker.',
