Cleanup never matched a live session because the controller registered empty
manifest and segment paths, renewal was a read-modify-write that could revert a
takeover, and the takeover script compared an ISO date to a number, so it errored.
- populate the session record's manifest and segment paths from the playlist path
- renew the lease via a Lua compare-and-set on the owning pod
- store the lease expiry as unix milliseconds so the scripts can compare it
- retain the session record past its lease so an orphan can still be taken over
- test the Redis store against a real Redis, including the renew-vs-takeover race
- drop the live stream record nothing ever read back
Live stream ownership is only tracked in process memory, so no replica can tell
which pod holds a stream open once that pod is gone.
- persist a LiveStreamSession record when the live stream mappings change
- delete the record when the stream is closed
- keep closing the stream when the store is unreachable
