feat(consolidation): trigger from log_work and status terminal transitions

log_work tool now invokes maybe_consolidate(reason='log_added') after a
successful create_log. The gate inside the consolidation service handles
threshold + setting checks.

update_note service snapshots old_status before mutation and fires
maybe_consolidate(reason='task_closed') when the status transitions into
'done' or 'cancelled'. Re-saving an already-terminal status doesn't
retrigger — only transitions count.
