PR Vision v0.1.1: rename from peptide-geo-monitor + P2 fixes

- Exhaustive rename: PGM_ -> PRV_, pgm_ -> prv_, text domain and
  slug peptide-geo-monitor -> pr-vision, admin menu GEO Monitor ->
  PR Vision, main file peptide-geo-monitor.php -> pr-vision.php,
  DB table pgm_ai_visibility -> prv_ai_visibility.
- P2-A: replace ltrim($host,'www.') character-mask with
  str_starts_with/substr prefix strip in PRV_Citation_Detector.
  Adds test coverage for wikipedia.org, webmd.com survival.
- P2-B: drop continue-on-error: true from PHPCS CI step;
  WordPress Coding Standards now gates the build.
- P2-C: remove dead in-run cache from PRV_Probe_Runner::run();
  each (peptide, intent, model) triplet is visited once per run,
  cache hit is structurally impossible.
- Version bump 0.1.0 -> 0.1.1 + CHANGELOG [0.1.1] entry.

 - **300-line limit** (enforced by CI). Split at the method boundary when approaching the limit.
