Remove the redundant TaskUpdated broadcast in TaskRunner.ContinueAsync's
queue-claim path, consolidate InteractiveLaunchSpecService's seven
MCP_TOOL_TIMEOUT literals into one constant (fixing the merge-helper handoff
spec's stale 200000ms value), and surface OpenQuickClaudeSession's two
failure cases via ErrorReported/footer instead of a silent no-op, with a
less ambiguous icon.
QueuePicker's raw-SQL Queued->Running claim bypasses TaskStateService.StartRunningAsync,
the only other place that broadcasts TaskUpdated on this transition, so the task-list
badge stayed on "Queued" until the run finished. Send TaskUpdated for alreadyClaimed
dispatches in TaskRunner.RunAsync/ContinueAsync to close that gap.
