Problem #
Agents cannot inspect Tangled pipeline or Pages state through tang; ephemeral logs, unassigned runners, and split HTML/asset propagation are hard to distinguish.
Acceptance criteria #
- Add pipeline list/view/logs/watch and supported retry/cancel surfaces.
- Distinguish queued, unassigned, running-without-output, failed, completed, and expired-log states.
- Add Pages status/watch/verify commands.
- Pages verification checks embedded source revision plus every referenced asset.
- Commands are useful in noninteractive and JSON workflows, with explicit unsupported diagnostics when the server lacks an API.
