Remove invisible control characters from the instruction file trivial effort

# strip bidi/zero-width controls (keeps a leading BOM):
perl -CSD -i -pe 's/[\x{202A}-\x{202E}\x{2066}-\x{2069}\x{200B}-\x{200D}\x{2060}]//g' .cursorrules

Treat untrusted instruction files as hostile low effort

Suppress a confirmed non-issue with a committed .pullguardignore entry (pullguard ignore locally, or comment /pullguard ignore <fingerprint> <reason> on the PR — the fingerprint is printed in the PR comment’s Triage section). Entries support expiresAt for time-boxed snoozes.

Security findings at major or critical severity — and any critical finding — always surface: .pullguardignore cannot hide them. The reviewed paths that keep them visible are acknowledged (reviewed, stays in reports) and, for a confirmed false positive, a reasoned false_positive entry — visible and audited, excluded only from the merge block.
