[Feat] Re-enable Requesty with current model support

[roomote-community]

Opened on behalf of Matt Rubens. Follow up by mentioning @roomote, in the web UI, or in Discord.

What changed

• Re-enabled Requesty in the provider connection UI.
• Updated Requesty's curated catalog to 12 current models.dev-supported models using Requesty's provider-local model slugs.
• Added current coding, helper, exploration, review, and planning defaults based on Claude Sonnet 5, Gemini 3.6 Flash, and Claude Opus 5.
• Updated model catalog and provider behavior coverage for the current Requesty IDs.

Why this change was made

Requesty was hidden when its models.dev catalog exposed too few recommended models. Its catalog now includes a useful current selection, so Roomote can offer Requesty again with valid defaults and model metadata.

Impact

Users can connect Requesty from setup or Settings > Models and start with a curated set of current supported models. Existing Requesty credentials continue to use the same REQUESTY_API_KEY integration.

1 issue outstanding. See task

• packages/types/src/model-provider-config.ts:371 Existing Requesty deployments can retain old IDs such as requesty/anthropic/claude-haiku-4-5, but the new provider-local catalog no longer contains those slugs. Reconnecting does not add or migrate the new models because buildAutoAddedTaskModelSettings exits when any Requesty model already exists, so tasks continue sending an unavailable legacy model ID. Add a migration/alias or replace existing Requesty model settings when the provider is updated.
