fix(docs): strip .mdx extensions from generated docs links

[devin-ai-integration]

Summary

Every cross-reference in the generated docs 404s on the docs site. Speakeasy emits relative links that keep the file extension:

| `request` | [operations.SendChatCompletionRequestRequest](../../models/operations/sendchatcompletionrequestrequest.mdx) | ...

Mintlify serves pages at extensionless paths, so the rendered href
/docs/client-sdks/typescript/models/operations/sendchatcompletionrequestrequest.mdx returns 404 while the same path without .mdx returns 200. That affected 1,139 links across 526 files — i.e. the type link on every operation page, e.g. https://openrouter.ai/docs/client-sdks/typescript/sdks/chat/README#send.

Changes:

• scripts/fix-docs-links.sh — post-generation pass that rewrites ](<path>.mdx) → ](<path>) (anchors preserved: foo.mdx#bar → foo#bar) across docs/**/*.mdx. Bash + grep + sed only, idempotent, and --check reports offending files without editing.
• Ran it, hence the bulk one-line-per-link diff.
• Wired it in next to the existing scripts/gen-docs-nav.sh step in speakeasy_run_on_pr.yaml, and added a docs-nav.yaml workflow (mirroring the one python-sdk/go-sdk already have) so the nightly sdk_generation.yaml regen PR — which never runs the repo's docs post-processing scripts — gets both the nav regen and the link fix auto-committed before it merges. Without that, Speakeasy re-adds the extensions on the next regen.

Companion PRs, identical fix: OpenRouterTeam/python-sdk and OpenRouterTeam/go-sdk (same bug in both, e.g. /docs/client-sdks/go/models/components/chatrequest.mdx).
