fix(openrouter): sort models by name to be more deterministic (#64)

* fix(openrouter): sort models by name to be more deterministic

Looks like OpenRouter returns models at a random order. Sort by name
to make the process of generating `openrouter.json` more deterministic.

Changes between runs can still happen, specially when it comes to cost,
but the diff will be small and easier to review.

* chore: add a taskfile

* chore: re-generate `openrouter.json` with sorted name
