Fix #5175: Add missing clipboard copy for task sharing URL

[roomote]

Summary

Fixes #5175 - Task sharing URL not being copied to clipboard after successful share.

Problem

When users successfully shared a task through the Share button, the sharing URL was not being copied to the clipboard as expected. The issue was that while the share functionality was working correctly (authentication, API calls, notifications), the final step of copying the URL to the clipboard was missing from the implementation.

Solution

• Added clipboard copy functionality: Added in the success path of the case in
• Comprehensive test coverage: Added tests to verify:
  • Clipboard copy occurs on successful share
  • No clipboard copy on failure
  • Error handling for missing tasks
  • Exception handling for clipboard operations
• Fixed test infrastructure: Corrected vscode module mocking to include the property for proper test execution

Testing

• ✅ All existing tests pass
• ✅ New tests verify clipboard functionality works correctly
• ✅ Linting and type checking pass
• ✅ Manual testing confirms clipboard copy works as expected

Files Changed

• - Added clipboard copy functionality
• - Added comprehensive test coverage

Impact

Users will now have the task sharing URL automatically copied to their clipboard when they successfully share a task, improving the user experience and matching expected behavior.
