v0.13.9

FreeLLMAPI v0.13.9 keeps retired models out of routing, tightens idempotent retries, fixes the CLI's default port and adds a Russian README.

## Routing

- **Retired models stay retired after a restart.** When a provider answers a model with 410 (end of life), FreeLLMAPI retires it. A restart used to undo that, so the dead model went back into rotation and failed again. Retirements now survive restarts and are only lifted by a newer catalog. Thanks @suantea, and @AlexQiu-coder for the report. (#1394, #1421)
- **Asking for a retired model by name no longer fails every time.** A request that names a model the provider has retired now falls through to the next model in your chain. The `X-Routed-Via` header shows which model answered. (#1394, #1423)

## API

- **Idempotent retries check every generation option.** Retrying with the same `Idempotency-Key` but a different `response_format`, `seed`, `stop` or `parallel_tool_calls` now returns `409 idempotency_key_conflict` instead of replaying the earlier answer. Keys stored before this update return a conflict once, then work as before. Thanks @ac1982. (#1440)

## CLI

- **`npx freellmapi` defaults to port 3001**, the gateway's port, when no `--url` or `FREELLMAPI_URL` is set. Published as `freellmapi@0.8.1` on npm. Thanks @agammann. (#1437)
- The CLI test suite now passes on Windows. Thanks @suantea. (#1424)

## Keys

- **CSV key import handles line breaks inside quoted fields**, so a label containing a line break no longer splits the row. Thanks @Claven07. (#1384)

## Docs

- **Russian README.** Thanks @The88788. (#1463)
