fix: address PR #173 security and code quality feedback

Security fixes:
- Enhanced branch name sanitization for cross-platform filesystem safety
  (handles Windows-invalid chars, reserved names, path length limits)
- Added branch name validation in pr-info.ts to prevent command injection
- Sanitized prUrl in kanban-card to only allow http/https URLs

Code quality improvements:
- Fixed placeholder issue where {owner}/{repo} was passed literally to gh api
- Replaced async forEach with Promise.all for proper async handling
- Display PR number extracted from URL in kanban cards
