DingTalk can receive interactive card callbacks, but the card UI still depends on a published template, so the adapter now supports a template-backed card path with text commands as the reliable fallback. Telegram and WeChat use the same allow-once, allow-always, and deny semantics so manual authorization behaves the same across platforms.
Constraint: DingTalk button rendering requires an operator-provided interactive card template id
Rejected: Treat the existing AI streaming card template as a permission card | it cannot guarantee visible action buttons
Confidence: high
Scope-risk: moderate
Directive: Do not remove the text approval fallback unless DingTalk card template provisioning is guaranteed

DingTalk uses QR registration to store client credentials, then reuses the existing IM pairing and session bridge. The merged main implementation keeps the existing WeChat QR binding path intact while adding DingTalk as a peer IM platform. The default IM workdir now falls back to the local user working directory so a newly bound chat can start immediately even when recent-project history is empty.
Constraint: Local main already carries WeChat IM, so the merge keeps WeChat config, QR binding, sidecar args, and unbind behavior intact while adding DingTalk.
Rejected: Keep empty defaultProjectDir as project-picker-only | newly bound IM users can hit a dead end with no recent projects.
Confidence: high
Scope-risk: moderate
Directive: Keep IM platform unions synchronized across config, pairing, sidecar args, desktop settings, and docs.

Not-tested: quality:pr full gate was blocked by existing local main CLI-core diff requiring allow-cli-core-change maintainer approval; live post-fix DingTalk second-message delivery was not repeated after the merge.
