feat: Add repository URI to statusline after branch name (#1977)

Adds the git repository URI to the statusline display, positioned
directly after the branch name indicator.

Changes:
- Extract repository URL using 'git remote get-url origin'
- Format URI by removing protocol prefix (https://, git@) and .git suffix
- Display shortened URI in brackets with cyan color: [github.com/user/repo]
- Gracefully handle repos without remotes (no display if no remote)
- Works correctly in both main repository and worktrees

Testing:
- Tested with HTTPS URLs: displays correctly
- Tested with SSH URLs: formats properly ([email protected]:user/repo → github.com/user/repo)
- Tested in worktree directory: works as expected
- Tested in main repository: displays correctly
- No regressions in existing indicators

Documentation:
- Updated STATUSLINE.md indicators table with new Repository URI entry
- Updated examples to show new URI display format
- Added breakdown explanations for repository indicator

Fixes #1976
