📝 WalkthroughWalkthroughThe temporary cache monitor now uses a configurable check interval and rebuilds file and directory snapshots before cleanup. It verifies file versions before deletion, retries eligible failures, and removes eligible empty directories. ChangesTemporary cache monitoring

In `@core/temp_monitor.py`:
- Around line 62-70: Clamp the value assigned to self.check_interval in the
interval_minutes validation branch to at least one second, so positive
sub-minute configuration values cannot produce a zero timeout in
_periodic_cleanup_loop. Preserve the existing validation and default interval
behavior.
- Around line 234-253: Update `_cleanup_empty_dirs` to skip directories whose
modification time is within `file_protection_seconds` before calling `rmdir()`.
Check each directory’s `st_mtime` during cleanup and preserve the existing
behavior for unprotected directories.

Reviewed the CodeRabbit docstring coverage warning. I am not expanding this PR to add docstrings across pre-existing touched functions: it is not a required repository CI check, does not affect the cleanup behavior being fixed, and would introduce unrelated churn. The two actionable stability findings were accepted and fixed in d270c49 with regression tests. |

- Line 447: Update _get_oldest_files to accept an optional exclusion set and
skip cached paths present in it, then pass attempted_paths when selecting
size-limit candidates so previously failed or changed files do not block cleanup
progress.

- Around line 215-216: Update _get_oldest_files so it logs the protected-files
warning only when no eligible files remain and no exclusions were supplied;
preserve the existing selection behavior and let cleanup() report failed
deletions for excluded candidates.
