fix(scripts): retain web_fetch in OpenRouter tool-capability codegen

[AlemTuzlak]

Problem

generateChatToolCapabilitiesType() in scripts/convert-openrouter-models.ts emitted only readonly ['web_search'] for the OpenRouterChatModelToolCapabilitiesByName mapped type. The committed packages/ai-openrouter/src/model-meta.ts correctly declares readonly ['web_search', 'web_fetch'], so the next regeneration of the model meta would have silently dropped web_fetch from every chat model's tool capabilities.

Both web_search and web_fetch are real OpenRouter gateway tools available across all chat models (see packages/ai-openrouter/src/tools/web-search-tool.ts and web-fetch-tool.ts).

Fix

• Emit readonly ['web_search', 'web_fetch'] from the codegen so regenerating model-meta.ts matches the committed source.
• Update the doc comment to mention both plugins.

Notes

Script-only change — no published package output changes (the committed model-meta.ts already has the correct value), so no changeset is needed.

📝 Walkthrough

Walkthrough

The pull request updates a TypeScript code generation script to extend OpenRouter chat model tool capabilities. The generateChatToolCapabilitiesType() function now emits type definitions annotating each chat model with both web_search and web_fetch tool capabilities instead of web_search alone.

Changes

OpenRouter Tool Capabilities Expansion

Layer / File(s)	Summary
Extend chat tool capabilities type scripts/convert-openrouter-models.ts	The OpenRouterChatModelToolCapabilitiesByName mapped type is updated to extend the tool-capability tuple from readonly ['web_search'] to readonly ['web_search', 'web_fetch'] for each chat model.

Poem

🐰 A script did whisper, "More tools for the chat!
Web search was lonely, so now web fetch's at bat,
Two capabilities dance in the tuple so tight,
OpenRouter's models now see more light." ✨
