fix(types): add TypeScript declarations for JS modules

Add .d.ts files for all JS modules imported by TypeScript source to resolve
TS7016 errors. Files are force-added because src/**/*.d.ts is gitignored.

- preferences, preferences-models, gitignore, agentic-docs-scaffold
- doc-checker, code-intelligence, native-git-bridge, paths, repo-identity
- types, trace-collector, doctor, url-utils, config
