Removes the dashboard's stuck-task tagging per operator request: the Stuck
card/status badges, stuck row styling, the footer Stuck segment and
stuckTaskCount stat, utils/taskStuck.ts, the isStuck agent-activity gate,
and the taskStuckTimeoutMs prop plumbing (App -> Board/Lane/Column/
WorktreeGroup/MainContent -> TaskCard/ListView/ExecutorStatusBar). Stuck-task
tests are deleted or reconciled. The taskStuckTimeoutMs setting and the
engine's recovery sweeps (including the stuck-killed status) are unchanged —
the setting is engine-side only now.
Also repoints the FN-6756 liveness-gate ratchet's facade scans at
executor/task-executor-session-facades.ts, where the wave20 extraction moved
hasLiveSessionSurface/clearPhantomExecutorBinding (the two pre-existing red
tests on main).

Operators summing the lane-header executing counts saw 10 active cards
under a 9-slot concurrency cap and read it as a capacity breach. The
header unioned the shared Running predicate with the card activity-chrome
predicate, which glowed needs-replan parks (FN-8494) and fresh
planner-log windows (FN-8300) that hold no concurrency slot.
isTaskAgentActive's positive arm now delegates to the shared
isRunningAgentTask predicate (footer/admission truth) and Column headers
count only that predicate, so glow and counts are a strict subset of the
live-agent population. Idle replans render the existing "Queued to
revise" waiting label instead of activity chrome.
