feat: abstract GitLab/GitHub CLI usage (#10)

- Move resolveRepoPath to lib/utils.ts
- Update all tools to use createProvider() from lib/providers/
- Remove direct imports from lib/gitlab.ts
- Mark lib/gitlab.ts as deprecated
- All tools now work with both GitHub (gh CLI) and GitLab (glab CLI)
- Provider auto-detected from git remote URL
