[grade=B] fix: i18n detectLanguage RFC 7231 q-value compliance + stale test fixes

- Fix detectLanguage() to sort by HTTP q-values per RFC 7231 (was first-match-wins)
- Strict qvalue grammar: /^(0(?:\.\d{0,3})?|1(?:\.0{0,3})?)$/
- Exclude q=0 entries (not acceptable per RFC)
- Case-insensitive Q parameter name
- Fix 5 stale tests: zh/ja now supported (31 languages, not 5)
- Add 7 boundary regression tests for q-value parsing
- All 1781 tests pass

Codex grade: B (urn:ump:6yumklcezgiaemcg5t2mebuoi4w2n5dexozm4j7h5pu5g2s4p5ta)
