registry: register the 2 delisted-not-typo'd slugs

Both remaining "unregistered" slugs traced clean via
~/.ringer/openrouter-catalog.changes.jsonl added/removed events — neither
was a manifest typo:

- openrouter/poolside/laguna-m.1:free existed in the OpenRouter catalog from
  2026-07-09 until it was delisted 2026-08-01T23:13:22Z, hours before the
  prior commit's catalog check ran.
- openrouter/nousresearch/hermes-3-llama-3.1-405b:free existed from
  2026-07-09 until its free tier was delisted 2026-07-19 (the paid variant
  is still live).

Registers both so historical attempts resolve to their correct lab (Poolside,
Nous Research) even though the models are no longer orderable.
