feat(claude-code): add model catalog and provider settings types

[edelauna]

Related GitHub Issue

Closes: #757

Description

Adds the @roo-code/types definitions for the new "Claude Code (Subscription)" provider, the first of 7 sub-issues under the #756 epic. This is types/schema only — no runtime handler, UI, or auth wiring yet (those land in #758-763).

• packages/types/src/providers/claude-code.ts (new): claudeCodeModels catalog (7 models: Fable 5, Opus 4.8/4.7/4.6, Sonnet 5, Sonnet 4.6 + its [1m] 1M-context variant, Haiku 4.5), ClaudeCodeModelId, claudeCodeDefaultModelId. Runtime inputPrice/outputPrice are 0 (subscription-covered); real list prices are recorded as comments for reference.
• packages/types/src/provider-settings.ts: adds "claude-code" to the provider union, claudeCodeSchema (apiModelId + optional claudeCodeCliPath, no API key field), wired into the discriminated union, modelIdKeysByProvider, and MODELS_BY_PROVIDER.
• packages/types/src/providers/index.ts: export + getProviderDefaultModelId wiring.
• webview-ui/src/components/ui/hooks/useSelectedModel.ts: added a claude-code case. This was required, not optional scope creep — adding "claude-code" to ProviderName broke an existing exhaustiveness (satisfies) check in this hook's default branch, so a matching case was needed to keep the build green.

Model catalog grounding: contextWindow/maxTokens values are verified against live claude --model <id> --output-format json output (modelUsage[id].contextWindow / .maxOutputTokens) rather than copied from anthropic.ts, since the Agent SDK/CLI path reports different (generally lower) max-output caps than the direct API for the same model name. Pricing was cross-checked against Anthropic's live pricing page.

Test Procedure

• packages/types/src/__tests__/claude-code.spec.ts (new): default model exists, all models have inputPrice/outputPrice of 0, schema accepts empty object / claudeCodeCliPath, rejects unknown keys in strict mode, and the discriminated-union arm (apiProvider: "claude-code") parses correctly with and without claudeCodeCliPath.
• webview-ui/src/components/ui/hooks/__tests__/useSelectedModel.spec.ts: added coverage for the new claude-code branch (default model, custom model ID) to satisfy patch coverage.
• Full monorepo check-types (11 packages) and test suites for @roo-code/types and @roo-code/vscode-webview pass locally and in CI.

Additional Notes

This is a types-only foundation for the epic in #756. Downstream sub-issues (#758 message conversion, #759 core handler, #760 usage tracking, #761 CLI detection, #762 settings UI, #763 usage dashboard) build on top of what's added here.

Summary by CodeRabbit

• New Features

  • Added support for selecting and using the Claude Code provider in provider settings and model selection.
  • Introduced a default Claude Code model and a supported model list with capability details.

• Bug Fixes

  • Improved validation so provider settings accept valid Claude Code configurations and reject unexpected fields.
  • Updated model selection to correctly return the chosen Claude Code model or its default when none is set.

📝 Walkthrough

Walkthrough

Adds a new "claude-code" provider: a model catalog with zero-cost pricing, Zod schema wiring into provider-settings (discriminated and non-discriminated), default model id resolution, webview useSelectedModel support, plus tests. Also updates existing import/export tests to use generic removed-provider identifiers instead of claude-code.

Changes

Claude Code provider integration

Layer / File(s)	Summary
Model catalog packages/types/src/providers/claude-code.ts	Defines ClaudeCodeModelId, claudeCodeDefaultModelId ("claude-sonnet-5"), and claudeCodeModels with per-model capabilities and zero pricing.
Schema and registry wiring packages/types/src/provider-settings.ts	Adds "claude-code" to providerNames, new claudeCodeSchema, wires it into discriminated/non-discriminated providerSettingsSchema, updates modelIdKeysByProvider and MODELS_BY_PROVIDER.
Default model resolution and catalog tests packages/types/src/providers/index.ts, packages/types/src/__tests__/claude-code.spec.ts	Re-exports claude-code module, adds default-model-id switch case, and adds tests for model pricing defaults and schema validation.
Webview model selection webview-ui/src/components/ui/hooks/useSelectedModel.ts, webview-ui/src/components/ui/hooks/__tests__/useSelectedModel.spec.ts	Adds a claude-code switch case resolving selected model id/info, with tests for default and custom model selection.
Import/export test fixture updates src/core/config/__tests__/importExport.spec.ts	Replaces claude-code as example invalid/removed provider with generic identifiers in fixtures and assertions.

Estimated code review effort: 2 (Simple) | ~15 minutes
