v0.3.4 - Pipeline parsing and TUI fixes

What's Fixed

Pipeline Command

• Fixed JSON parsing errors when listing pipelines
• Made Repository model fields optional (slug, is_private, scm) to match API responses
• Added missing fields to pipeline models (trigger name, commit type/links)
• Fixed RepositoryLinks serialization with proper serde rename

TUI (Terminal User Interface)

• Implemented data loading functionality - TUI now actually fetches data from Bitbucket!
• Added methods to load repositories, pull requests, issues, and pipelines
• Implemented refresh capability with 'r' key to reload data in current view
• TUI now shows loading status during data fetch
• Requires workspace parameter: bitbucket tui --workspace <workspace>

Other Fixes

• Fixed Cargo.toml formatting issues
• Updated all code that uses Repository fields to handle Option types

Testing

All Bitbucket API operations verified working:

• ✅ Repository list and view
• ✅ Pipeline list (previously broken, now fixed)
• ✅ Pull request list
• ✅ Issue list
• ✅ TUI data loading and refresh
