docs(site): drop the duplicate lineage Detail header key (#502 + #504 collision)

[ScriptedAlchemy]

Why

#502 and #504 each restored the headers.detail key that #490 had removed, and both merged. website/plugins/generated-reference.ts now declares detail twice per locale, so pnpm docs:site:build fails on main at the typecheck step:

plugins/generated-reference.ts(173,7): error TS1117: An object literal cannot have multiple properties with the same name.
plugins/generated-reference.ts(255,7): error TS1117: An object literal cannot have multiple properties with the same name.

Change

Remove the second copy in each locale (the #504 lines), keeping #502's Detail / 说明. Two deleted lines; no page content changes beyond the zh header text returning to #502's wording.

Verification

• pnpm --filter @agent-bundle/docs typecheck passes locally.
• skip-changeset: private website package only.
