fix(worker,ui): clean up three review leftovers from the list-handler run

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.
