Branch names containing special characters (particularly parentheses)
were breaking markdown links in GitHub comments. This caused URLs to be
truncated when clicked.
Changes:
- Add encodeBranchName() helper function that:
- Uses encodeURIComponent for basic encoding
- Preserves forward slashes (GitHub expects literal / in branch URLs)
- Manually encodes parentheses (not encoded by encodeURIComponent per RFC 3986)
- Apply encoding to branch URLs in:
- update-comment-link.ts (PR compare URLs)
- branch-cleanup.ts (branch tree URLs)
- comment-logic.ts (branch tree URLs)
- comments/common.ts (branch tree URLs)
- Improve PR link regex to use greedy match with end anchor
- Add test for branch names with special characters
