Add cleanup for event listeners and intervals low effort

// Before: listener never removed
emitter.on('data', handler);

// After: cleanup on destroy
const handler = (data) => { ... };
emitter.on('data', handler);
onDestroy(() => emitter.off('data', handler));

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.
