Updated the PR state handling to use a consistent uppercase format ('OPEN', 'MERGED', 'CLOSED') throughout the codebase. This includes changes to the worktree metadata interface, PR creation logic, and related tests to ensure uniformity and prevent potential mismatches in state representation.
Additionally, modified the GitHub PR fetching logic to retrieve all PR states, allowing for better detection of state changes.
This refactor enhances clarity and consistency in how PR states are managed and displayed.
- Add comprehensive unit tests for SettingsService, covering global and project settings management, including creation, updates, and merging with defaults.
- Implement tests for handling credentials, ensuring proper masking and merging of API keys.
- Introduce tests for migration from localStorage, validating successful data transfer and error handling.
- Enhance error handling in subprocess management tests, ensuring robust timeout and output reading scenarios.
- Added tests to ensure mkdirSafe handles ELOOP and EEXIST errors gracefully.
- Implemented checks for existsSafe to return true for ELOOP errors and throw for other errors.
- Improved overall robustness of filesystem utility tests.
