* feat(frontend): pin recent chats * fix(threads): address pin-chat review feedback - Stop bumping updated_at on metadata-only PATCH (pin/unpin) via a new update_metadata(touch=False) path so unpinning no longer jumps a chat to the top of the updated_at-sorted recent list. - Narrow patchThreadMetadata to a ThreadMetadataPatchResponse matching the Gateway's actual response (no values/context). - Namespace the pinned metadata key as deerflow_pinned for consistency with deerflow_sidecar / deerflow_branch. - Cover touch/touch=False behavior in repo + router tests; document the e2e mock's updated_at preservation now mirrors production. * style(frontend): format thread utils test * fix(threads): make pinned ordering server-side * test(frontend): keep infinite-scroll fixture order stable * test(frontend): stabilize lark reconnect e2e * docs: clarify thread pin metadata contract
