feat(claude-code): expose settings and loaded skills

[mikemikimike]

Changes

Closes #1113.

• Adds settingSources to ClaudeCodeTextConfig and forwards it to Claude Code's --setting-sources flag.
• Surfaces the SDK init message's loaded skills in the existing claude-code.session-id custom event.
• Preserves the prior default setting source (user) and normalizes omitted SDK skills to an empty array.

Checklist

• I have followed the steps in the Contributing guide.
• I have tested this code locally with pnpm run test:pr. It was started, but the unrelated React Native Expo smoke stage did not complete locally.

Release Impact

• This change affects published code, and I have generated a changeset.

Test plan

• pnpm --filter @tanstack/ai-claude-code test:lib -- --run tests/text-adapter.test.ts tests/translate.test.ts
• pnpm --filter @tanstack/ai-claude-code test:types
• pnpm --filter @tanstack/ai-claude-code test:oxlint
• pnpm --filter @tanstack/ai-claude-code test:build
• pnpm exec oxfmt --check ...
• git diff origin/main...HEAD --check

Summary by CodeRabbit

📝 Walkthrough

Walkthrough

The Claude Code adapter configures CLI setting sources and forwards loaded skills from SDK init messages through session metadata events. Tests cover custom sources, default sources, populated skills, and empty-skill defaults. A changeset documents the update.

Changes

Claude Code adapter updates

Layer / File(s)	Summary
Setting source configuration packages/ai-claude-code/src/adapters/text.ts, packages/ai-claude-code/tests/text-adapter.test.ts	Adds supported setting-source types and configuration. CLI arguments use configured sources and default to user. Tests cover project,local and the default.
Skill metadata forwarding packages/ai-claude-code/src/stream/sdk-types.ts, packages/ai-claude-code/src/stream/translate.ts, packages/ai-claude-code/tests/translate.test.ts, .changeset/pink-skills-dance.md	Adds optional SDK skill data and includes it in session metadata. Missing skills become an empty array. Tests cover both cases, and the changeset documents the update.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 27d3b

The change exposes Claude Code settings and loaded skills while preserving the existing default behavior and normalizing omitted skills; no actionable merge-blocking risk remains after normal checks and review.
