Editorial Lint / lint-editorial (push) Has been cancelled
feat(random): finalize multi-theme telemetry and polish
- document random theme exclusions, perf guard tooling, and roadmap completion

- tighten random reroll UX: strict theme persistence, throttle handling, export parity, diagnostics updates

- add regression coverage for telemetry counters, multi-theme flows, and locked rerolls; refresh README and notes

Tests: pytest -q (fast random + telemetry suites)
