fix: gossip correctness — debounce, non-blocking peer init, targeted sync
gossip.py: - _poll_loop: run initial baseline poll at startup, then debounce 2s after watchdog events so a 20-commit push triggers one broadcast not twenty - _on_announce: move inline _send_packet calls to _send_initial_refs() on a daemon thread — _send_packet blocks up to 15s waiting for a path, which was stalling the RNS announce handler when called inline - _trigger_sync: pass --seed NID@127.0.0.1:PORT to rad sync --fetch when rad node connect succeeded, targeting the specific peer that sent the gossip instead of syncing with all known seeds; log clearly when connect fails and fall back to untagged fetch tests/test_gossip.py: - test_seed_flag_added_when_connect_succeeds - test_no_seed_flag_when_connect_fails - test_debounce_clears_event_on_early_wakeup Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
