playwriter skill self improvement: reduce wasted context on JS-heavy sites

Browse Source 
Add explicit guidance to use playwriter first for JS-rendered websites and blocking overlays, based on repeated failures where webfetch/curl returned empty shells and screenshots were used too early.

Key updates:\n- Add a hard 'when to use playwriter vs webfetch/curl' rule in the main skill docs\n- Add a 'snapshot before screenshot' rule to prevent slow image-first debugging loops\n- Add a concrete anti-pattern for JS-rendered sites in common mistakes\n- Add obstacle-handling flow for cookie/login/age-gate overlays\n- Add media extraction/download pattern using evaluate + Node fetch/fs\n- Update skill frontmatter description (and well-known discovery copies) so context-loaded summaries also include the JS-heavy-site rule
