Android integrations: install/connect/uninstall stubs return not-implemented

[itsdestin]

Summary

The marketplace's "Connect your stuff" rail now renders on Android (mp-mobile branch). The catalog browse works, but every action button on an integration card fails with a not-implemented stub error.

Repro

1. Install the latest debug APK from a mp-mobile-derived build.
2. Open Marketplace → scroll to "Connect your stuff" rail.
3. Tap any integration (Gmail, Drive, Spotify, etc.).
4. Tap Install (or Connect / Uninstall if the card shows them).
5. Card status flips to Error, detail overlay shows: not-implemented: integrations available on Android in a follow-up.

What's working

• ✅ integrations:list — fetches catalog from https://raw.githubusercontent.com/itsdestin/wecoded-marketplace/master/integrations/index.json (24h cached). Implemented in app/src/main/kotlin/com/youcoded/app/skills/MarketplaceFetcher.kt::fetchIntegrations() and LocalSkillProvider.kt::listIntegrations(). Cards render correctly with platform-locked badges (e.g. macOS Only).

What's stubbed

In app/src/main/kotlin/com/youcoded/app/runtime/SessionService.kt (currently the case block matching "integrations:status", "integrations:install", "integrations:uninstall", "integrations:connect", "integrations:configure"):

IPC	Behavior
integrations:install	Returns { error: "not-implemented..." }
integrations:connect	Returns { error: "not-implemented..." }
integrations:uninstall	Returns { error: "not-implemented..." }
integrations:status	Returns { error: "not-implemented..." }
integrations:configure	Returns { error: "not-implemented..." } (also "Coming soon" on desktop — out of scope)

Implementation notes

Three pieces, in order:

1. Install (plugin-wrapped integrations) — port desktop/src/main/integration-installer.ts::install() to a Kotlin IntegrationInstaller. For setup.type === "plugin" entries (Google Workspace, Spotify, etc.) it should look up the entry via LocalSkillProvider/MarketplaceFetcher, route through the existing Android PluginInstaller (which already handles clone + four-registry write for skills), then mirror setup.postInstallCommand back so the renderer can show the SetupHintBanner.

2. Connect (OAuth) — Android has no Electron safeStorage equivalent. Reuse the EncryptedSharedPreferences already wired for marketplace:auth (see MasterKeys usage in SessionService.kt) for token-at-rest. Start with one provider (Google Workspace) and copy the desktop flow's redirect-uri / device-code handling. The desktop flow currently uses an OAuth web flow against the Cloudflare Worker, which has a separate bug filed about redirect_uri mismatch — that needs fixing first or in parallel.

3. Uninstall + Status — uninstall is the inverse of install + clear the encrypted token. Status reads the integrations manifest (~/.claude/integrations.json on desktop). Either mirror that path on Android or fold into the existing youcoded-skills.json.
