fix: refine regex patterns and improve utility functions for mention handling

- Updated regex patterns in chipUtils and mentionLinkify to enhance boundary detection for mentions.
- Refactored taskChangeRequest to simplify earliest date calculation using array destructuring.
- Improved taskReferenceUtils by replacing character boundary checks with a more concise regex.
- Enhanced teamMessageFiltering to ensure boolean checks for message filtering conditions.
- Adjusted urlMatchUtils to refine URL matching regex for better accuracy.
- Updated crossTeam constants to include comments for regex patterns, improving code clarity.
- Removed unused CommentAttachmentPayload type from api.ts to clean up type definitions.
- Introduced McpInstallScope type for better type safety in mcp.ts.
- Enhanced extensionNormalizers to improve URL normalization and added tests for parseGitHubOwnerRepo function.
- Cleaned up pricing.ts by removing unnecessary eslint disable comments.
- Added tests for new functionality in chipUtils and crossTeam constants, ensuring robust coverage.
