The collector's _SessionAggregator now resolves the asciinema shard
via find_shard_with_sid and stamps it onto every emitted
attacker.session.ended payload as `shard_path`. None when the shard
isn't on disk yet (collector race with sessrec flush) — consumers
treat that as "skip until next tick".
Additive field; existing TTP worker consumes the same topic and
ignores unknown keys, so no payload-version bump needed. Two new
tests pin the shard-found and shard-missing cases.
Unblocks BEHAVE-INTEGRATION Phase 4: the profiler worker reads
shard_path directly from the payload instead of disk-reaching.
