refactor(provider-grok): move Grok into its own provider package

[juliusmarminge]

Grok was the next provider still living inside apps/server. This moves it into @t3tools/provider-grok, built on the @t3tools/provider-acp package from #17354.

Package

• ./settings: GrokSettings, moved out of contracts.
• ./client: label, settings form, and a plain-data glyph. The hand-drawn GrokIcon and the mobile branch are gone; web and mobile draw the icon from the package.
• ./server: GrokDriver and GrokAdapterV2Driver.
• ./testing: the ACP flavor, runtime launch, status builders, text generation, usage reader, and xAI extension helpers. The server's replay testkit, the Grok fixture recorder, and orchestration tests drive these directly.

Boundaries

• The driver gets its cwd from ProviderHost instead of ServerConfig, and imports errors and event loggers from provider-core.
• effect-acp is a dev dependency, same as in the server, because the license scan walks production dependencies. refactor(provider-acp): move the shared ACP adapter into its own package #17354 has the same fix for provider-acp; that fix is what made its desktop build pass.
• These tests stay in the server: the adapter test (uses the orchestrator's project store and runtime policy), the status test (uses the shared ACP mock agent), and the title-generation test (uses a server fixture).

Verification

• Typecheck: provider-grok, provider-acp, provider-cursor, provider-opencode, server, web, mobile.
• Tests: the package (driver, skills, ACP support, CLI probe, xAI extension and background tasks), plus the server's Grok/ACP adapter, status, text-generation, registry, command-policy, replay-fixture, and web provider-icon tests. 445 passing.
• vp lint, knip:check workspaces.

📝 Walkthrough

Walkthrough

The change defines a dedicated Grok provider package with its own settings, client, server, and testing exports. Server, web, and mobile code now use the package entry points. The change also updates provider icons, repository checks, release-smoke fixtures, and documentation links.

Changes

Grok provider package

Layer / File(s)	Summary
Define the Grok package API packages/provider-grok/*, packages/contracts/src/settings.ts, package.json, scripts/release-smoke.ts, docs/internals/*	The new package defines Grok settings, client metadata, server and testing exports, and TypeScript configuration. The Grok settings schema is removed from contracts. Repository checks, release-smoke fixtures, and documentation links are updated.
Move Grok server modules into the package packages/provider-grok/src/server/*	Server modules now use package-local settings and support modules. The driver reads cwd from host.paths instead of the server configuration service. Tests use the updated module paths and test setup.
Connect server consumers apps/server/package.json, apps/server/src/*, apps/server/scripts/record-grok-acp-replay-fixture.ts	The server adds the package dependency and imports Grok drivers, settings, and testing helpers from package entry points. Server tests and the replay-fixture recorder use those imports.
Integrate web and mobile clients apps/web/package.json, apps/web/src/components/*, apps/web/src/components/settings/providerDriverMeta.ts, apps/mobile/package.json, apps/mobile/src/components/ProviderIcon.tsx, apps/mobile/src/lib/providerClients.ts	The web and mobile apps add the package dependency. The web settings registry and mobile provider registry use grokClient. The provider icon components remove their dedicated Grok icons and use existing fallback behavior.

Explanation

The description explains the package move, boundaries, and verification, but it omits the required Problem, Change, and Scope and approval sections. It also provides no explicit maintainer approval or exemption rationale and no before/after screenshots for the UI icon changes.

Resolution

Add the required template sections. State the problem and expected behavior, label the implementation details under Change, link the triaged issue or maintainer approval, or explain why an exemption applies, and add before/after screenshots for the icon changes.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This is largely a mechanical extraction of the existing Grok provider, with defaults and provider behavior preserved. The new package’s server code imports runtime modules listed only as development dependencies, creating a plausible production-install failure that needs human review.

Notes:

• All code in this push has already been reviewed. Approvability was decided on eligibility alone.

No code changes detected at d6093c2. Prior analysis still applies.
