replaces hardcoded time.Sleep(500ms) with deterministic polling
via `ipfs pubsub ls`, following the pattern established in p2p_test.go
addresses review feedback from #11110
- upgrade go-libp2p-pubsub to v0.15.0
- add persistent seqno validator using BasicSeqnoValidator
stores max seen seqno per peer at /pubsub/seqno/<peerid>
survives daemon restarts, addresses message cycling in large networks (#9665)
- add `ipfs pubsub reset` command to clear validator state
- add `ipfs diag datastore get/count` commands for datastore inspection
requires daemon to be stopped, useful for debugging
- change pubsub status from Deprecated to Experimental
- add CLI tests for pubsub and diag datastore commands
- remove flaky pubsub_msg_seen_cache_test.go (replaced by CLI tests)
