Fix TypeScript CI failure for fumadocs workspace app

[Copilot]

CI was failing because the root TypeScript check was attempting to validate apps/docs files using the root tsconfig.json, which has incompatible path mappings (~/* vs @/*).

Changes

• tsconfig.json: Exclude ./apps directory from root TypeScript compilation
• .github/workflows/ci.yml: Add separate type check step for docs workspace
  • Mobile: npx tsc --noEmit (root)
  • Docs: cd apps/docs && npx tsc --noEmit

Each workspace app (fumadocs, future apps) now uses its own TypeScript configuration independently.

Changes:

• Excludes ./apps from the root tsconfig.json compilation scope.
• Splits CI TypeScript checks into separate steps for Mobile (root) and Docs (apps/docs).

The docs type-check step runs npx tsc --noEmit, which may not match the docs app’s intended type-check pipeline (types:check runs fumadocs-mdx && next typegen && tsc --noEmit). Consider invoking the workspace script (or pnpm ... exec tsc) so CI uses the docs package’s local TypeScript version and required pre-typegen steps, avoiding false negatives/positives.

Suggested change

	run: cd apps/docs && npx tsc --noEmit
	run: pnpm --filter ./apps/docs types:check
