Rongsong Shen 5a36698a90 docs(raft-ha-core-safety): bug-1282+bug-1286 verified fixed; unmask round-4 election cross-deny (task 5.5) 
6-round chaotic soak with both fixes: rounds 1-3 elect; round 4 has NO segfault,
NO fdatasync, NO iomgr deadlock — both fixes held. The round-4 stall is now the
pure election-liveness cross-deny that the crash/deadlock masked: the freshest
survivor (floor 15) is the legitimate winner, but the other survivor (floor 12)
denies it on eligibility because it still believes its dead primary is alive
(in_catch_up + heartbeat-not-yet-stale). Suspect 5.2's last_activity re-arm
keeping a node falsely-fresh after primary death.

Adds task 5.5 (release the heartbeat-fresh/in_catch_up deny on genuine primary
death within the failover window) as the remaining 7.2 blocker. bug-1282 and
bug-1286 are fixed and verified; consensus safety unaffected.
