[WIP] Refactor pull request #170 for clean merge

[Copilot]

Optimize API calls by combining access check and folder listing

Performance Improvement

Extracts the valuable optimization from PR #170 without the regressions.

Reduces API calls from 2 to 1 on every sync:

• Before: check_api_access() + list_existing_folders() = 2 API calls
• After: verify_access_and_get_folders() = 1 API call (50% reduction)

Changes Made

• Add verify_access_and_get_folders() function with proper error handling
• Update sync_profile() call site to use combined function
• Update 6 test functions in test_main.py
• Update 3 test mocks in tests/test_parallel_deletion.py
• Keep list_existing_folders() for backward compatibility
• Tests passing

Implementation Details

The new function:

• Returns Dict[str, str] on success, None on auth/network failure
• Handles 401/403/404 errors with appropriate logging (no retry)
• Implements exponential backoff retry for 5xx errors
• Properly sanitizes profile_id in error messages

Why Not Merge PR #170 Directly?

PR #170 has unrelated histories and includes regressions:

• ❌ Removes .env auto-fix security feature
• ❌ Removes enhanced log sanitization
• ❌ Removes RTLO/Bidi spoofing prevention
• ❌ Removes parallel folder deletion
• ❌ Deletes 500+ lines of tests

This PR extracts only the valuable optimization cleanly.

Hi @copilot, I received an error indicating that changes were pushed to the Copilot branch while you were working, which prevented you from successfully merging your changes with the remote branch.

I've successfully re-implemented the optimization in commit 8739375. The changes combine the API access check and folder listing into a single request, reducing API calls by 50%.

What was done:

• Added verify_access_and_get_folders() function
• Updated sync_profile() to use the combined function
• Updated all tests (6 functions in test_main.py, 3 mocks in test_parallel_deletion.py)
• All tests passing

The merge conflict issue:
The branch has diverged because earlier work wasn't successfully pushed. The current local commit 8739375 contains the clean implementation based on main branch (75bc5fd), while the remote has different history.

To resolve:
You'll need to force-push this branch or create a new PR from this commit. The changes are ready and tested - they just need to be pushed to override the old remote branch history.
