Non-destructive pre-declares "don't touch the disks" on Start: the
Storage stage skips wipe-probe, badblocks -w, and write-mode fio,
and reports a read-only summary. Runs a new non_destructive column;
threaded through Claim → agent tests.Deps → Storage stage.
Cancel halts an in-flight run. The orchestrator transitions to a
new StateCancelled via TriggerOperatorCancelled (valid from any
active state); the agent's next heartbeat returns cmd=cancel_stage,
which fires a stored CancelFunc on the per-stage context. Stage
subprocesses spawned with exec.CommandContext die with the context,
the agent posts a cancelled outcome, then powers the host off.
Destructive stages mid-run may leave the host in an intermediate
state — the UI confirm dialog warns the operator; recovery is
manual for now.

Click a tile to open /hosts/{id} — the canonical control surface per
host. Timeline renders every pre-stage, stage, and terminal node in
order, with the current one pulsing, failed ones flagged, and
downstream ones dimmed as skipped. Detail page shows summary, hold
card (when holding), all action buttons, spec diffs, a full-height
log pane, and a collapsed expected-spec YAML.
Tile slims to name, last-seen, status, and one primary action; a
CSS-overlay <a> makes the whole card clickable while buttons stay
receptive via z-index.
Runner.publishTileUpdate now also emits pipeline-{runID} fragments,
and CompleteStage wraps Stages.CompleteByName so stage completions
advance the timeline live — without this the dots only moved on
state transitions.
