0.8.79

Added

• Durable cross-process rate-limit admission. Harn now exposes
  durable_rate_limit_acquire(options) for SQLite-backed sliding-window quota
  reservations across processes, with atomic multi-bucket admission, structured
  timeout results, and mock-clock-friendly tests (#1873).

Changed

• LLM provider rate limiting now consumes catalog rate_limits metadata,
  including model-specific RPM/TPM and route concurrency, with environment and
  llm_rate_limit overrides for paid/custom quotas.
• Durable LLM rate-limit admission. Catalog and runtime LLM RPM/TPM
  limits now use shared SQLite admission by default across Harn processes, so
  parallel eval runners and worker fleets respect one provider/model quota
  without relying on per-process sleeps or ad hoc environment-only guardrails
  (#1873).
