fix(security): keep only the regex sanitization; drop non-functional CodeQL annotations

The lgtm[]/nosemgrep: comments in codexIdentity.ts and reasoningCache.ts use
formats GitHub Actions CodeQL does not honor, and shifting those sha256 lines
re-attributed the already-dismissed base alerts to this PR as two new CodeQL
findings. Revert those two annotation-only files to base so the existing
dismissals apply; retain the real fix (escaping backslash in the test regex),
which resolves the open js/incomplete-sanitization alert.
