feat: docs: add Lark / Feishu adapter

[mazhe-nerd]

Summary

Adds @larksuite/vercel-chat-adapter, the Lark / Feishu adapter for Chat SDK, as a vendor-official community adapter.

• Package: @larksuite/vercel-chat-adapter — published on npm under the official larksuite scope
• Built on: @larksuiteoapi/node-sdk's LarkChannel, the official Lark Node SDK
• Docs source: external README referenced by adapters.json lives in larksuite/node-sdk (the official Lark vendor-owned GitHub org, pinned at commit cbc4adf1); the in-tree MDX in this PR is the rendered detail page (mdxBody: true)
• Capabilities: native cardkit typewriter streaming, interactive cards, reactions, edit / delete, message history (via SDK normalize()), DM detection, mention handling, and scan-to-create app onboarding through registerLarkApp

Changes

File	Change
apps/docs/adapters.json	Add Lark / Feishu entry (community: true, vendorOfficial: true)
apps/docs/content/adapters/vendor-official/lark.mdx	New hand-authored MDX detail page (frontmatter with full features matrix, install / quick start / configuration / transport / streaming / ID encoding / history / safety / limitations / FeatureSupport)
apps/docs/content/adapters/vendor-official/meta.json	Append "lark" to the sidebar pages array
packages/integration-tests/src/docs-adapters.test.ts	Append "lark" to the hardcoded vendor-official slug list asserted by Vendor-Official adapter MDX › contains exactly the expected adapters

No icon registered in adapters.json / iconMap / adapterLogos — matches the existing pattern for vendor-official adapters (Beeper, Resend, Liveblocks, Zernio, Photon).

Vendor Official tier

Per docs/contributing/building.mdx (Qualifications for vendor official tier):

• ✅ Commitment for continued maintenance — owned by the Lark / Feishu team
• ✅ GitHub hosting in official vendor-owned org — adapter README lives in larksuite/node-sdk, the official Lark org
• ✅ Documentation in primary vendor docs — will be cross-linked from the official Lark Open Platform developer documentation
• ✅ Announcement — will be announced through Lark developer changelog / channels

A note on source visibility

The adapter source is not currently open-sourced due to internal release-process requirements. What is public:

• The npm package itself (consumable by any user)
• The README, hosted in larksuite/node-sdk (official Lark org)
• The underlying @larksuiteoapi/node-sdk on which it is built — this is fully open-source

Test plan

• pnpm --filter docs build — docs app builds cleanly; /en/adapters/vendor-official/lark and /en/adapters/vendor-official/lark/og routes are generated
• pnpm typecheck — passes (33 tasks)
• pnpm check (Ultracite / Biome) — 438 files, no fixes
• pnpm --filter @chat-adapter/integration-tests test docs-adapters — 232 tests pass (frontmatter, vendor-official roster, adapters.json ↔ MDX sync)
• Manual: /adapters lists the Lark / Feishu card in the Vendor Official section; /adapters/vendor-official/lark renders the MDX detail page with the FeatureSupport matrix

A member of the Team first needs to authorize it.

Thanks @mazhe-nerd! Can you send us a link to the blog post about the adapter?

[mazhe-nerd]

Thanks @bensabic ! The adapter is currently documented at https://github.com/larksuite/node-sdk/tree/main/docs/vercel-chat-adapter under the official Lark org. Happy to add a more formal announcement (blog post / changelog / social) if that's what you're looking for — let me know which channel works best.

Thanks for the quick response! If you can publish it on the blog, that'd be great

@bensabic The integration guide is now live on the Lark Open Platform docs:

• Lark: https://open.larksuite.com/document/mcp_open_tools/integrating-agents-with-feishu/vercel-chat-sdk-lark-message-publish
• Feishu : https://open.feishu.cn/document/mcp_open_tools/integrating-agents-with-feishu/vercel-chat-sdk-lark-message-publish

It walks through how to integrate Feishu using Vercel Chat SDK — install, quickstart, app onboarding via
scan-to-create — and references @larksuite/vercel-chat-adapter throughout. It sits alongside the existing Feishu
Channel SDK guide as a sibling page in the official docs tree. Hope this satisfies the vendor-official announcement
criterion.

Thanks for taking the time to review this PR and for the clear feedback along the way!
