Note

Low Risk
Import and typing refactors only; provider-instance routing and service behavior are unchanged, with broad test coverage noted in the PR.

Overview
This PR mechanically aligns the review and text-generation domains with the repo’s target Effect Context.Service pattern without changing routing or generation behavior.

TextGeneration now defines its API on the service tag itself (replacing a separate TextGenerationShape interface), builds registry-backed implementations via TextGeneration.of, and exposes a make effect plus a layer wired as Layer.effect(TextGeneration, make). A deprecated TextGenerationShape alias remains for legacy consumers. ReviewService follows the same move: the standalone shape type is removed, make is a plain Effect.gen, and the layer references that effect directly.

All provider implementations (Claude, Codex, Cursor, Grok, OpenCode) and ProviderDriver now satisfy TextGeneration.TextGeneration["Service"] instead of the old shape type. Tests and harnesses (GitManager, ProviderAdapterRegistry, text-generation tests, etc.) switch to namespace imports (* as Module) for services, config, GitHub CLI, and related helpers so tokens and errors are referenced in a consistent, module-qualified way.

Note

Refactor text generation and review services to use namespace imports

• Replaces named imports with namespace imports across all text generation providers (ClaudeTextGeneration, CodexTextGeneration, CursorTextGeneration, GrokTextGeneration, OpenCodeTextGeneration) and the ReviewService, aligning import style with Effect.js conventions.
• Replaces the separate TextGenerationShape interface with an inline Context.Service-based TextGeneration class; exports TextGenerationShape as a deprecated type alias for backward compatibility.
• Adds a standalone make effect to TextGeneration.ts and simplifies the layer to Layer.effect(TextGeneration, make).
• Updates ReviewService to inline its service shape via Context.Service generic and changes make from a function returning an Effect to a plain Effect.
• Updates all test helpers and DI wiring in GitManager.test.ts and ProviderAdapterRegistry.test.ts to use namespaced service tokens (e.g. ServerConfig.ServerConfig.layerTest).
