Adds a Flow Completed span carrying flow_name, duration_ms and outcome,
emitted when a flow finishes or fails. Elapsed time comes from a monotonic
stamp taken at flow start and cleared on use.
Kept separate from the Flow Execution span rather than holding that one open:
it is emitted and closed at start and the daily aggregate counts it, so
holding it would drop every run that is killed or crashes from the execution
count. A killed run now simply has no Flow Completed row, and the count is
unaffected.
Elapsed time is an explicit duration_ms attribute rather than the span's own
duration, which the ingestion pipeline stores as a suffixed string
("0.0000184s") that downstream aggregation parses to zero.

A flow reported only that it started. FlowFinishedEvent, FlowFailedEvent,
MethodExecutionFailedEvent, MethodExecutionPausedEvent and FlowPausedEvent all
reached the console formatter and stopped there, and FlowInputRequestedEvent,
FlowInputReceivedEvent and ConversationTurnFailedEvent had no listener at all -
so success rate, failure rate and every HITL pause were unmeasurable.
Adds flow:completed, flow:failed, flow:method_failed, flow:paused,
flow:hitl_paused, flow:input_requested, flow:input_received and
flow:conversation_turn_failed as feature-usage spans, which the existing
feature-usage aggregation already reads.
Deliberately does not hold the Flow Execution span open to measure duration:
flow_executions_daily_target counts those spans at start, so a run that never
finishes would disappear from the count entirely. Duration needs its own span.
Counts only - flow names, method names, error text and flow state are never
recorded.
