chore(repo): nest quality-gate state under config/quality, declutter root (#3896)

Move the committed quality-gate state files out of the repo root into
config/quality/ and the v3.8.24 documentation audit into docs/ops/, then
re-point every gate script, test and .gitignore entry at the new paths.
Refresh docs/architecture/REPOSITORY_MAP.md (stale since v3.8.2) to match
the current layout.

Moved -> config/quality/:
  quality-baseline.json, complexity-baseline.json, duplication-baseline.json,
  file-size-baseline.json, test-discovery-baseline.json,
  dependency-allowlist.json, .license-allowlist.json
  (generated quality-metrics.json now written here too; still gitignored)

Moved -> docs/ops/:
  DOCUMENTATION_AUDIT_REPORT.md (+ meta.json entry + fabricated-docs skip)

Path updates: check-{complexity,duplication,file-size,test-discovery,deps,
licenses,dead-code,cognitive-complexity,type-coverage}.mjs, check-quality-
ratchet.mjs, collect-metrics.mjs, check-tracked-artifacts.mjs (+ its test and
check-deps test). Also gitignore /logs/ (was untracked-not-ignored).

Tracked root files: 56 -> 48. Tool configs left in root on purpose: most are
auto-discovered there, and the tsconfig variants have location-relative
files:[] arrays that would need 46 path rewrites for a 2-file gain.
