Rongsong Shen 9344b8ed60 docs(raft-ha-core-safety): document term-blind bypass safe-by-guard + pin restart identity (task 6.2) 
The term-blind ha_apply_single_entry direct-persist branch (carried
forward from task 2.4) is unreachable with a real non-zero term in any
current production path: its only trigger, raft_send_append_entries,
has zero production call sites (library simulator only). Both real
senders (repl_broadcast, ha_stream_wal_to_standby) always emit a
non-zero term for a present LSN. Documents this in ha.c and design.md
rather than structurally retiring a dormant path (YAGNI), with an
explicit flag for future re-evaluation if a heartbeat-driver task ever
wires up raft_send_append_entries.

Adds two regression pins: restart preserves (term,lsn) identity
(replay_wal already reconstructs the term index via record_entry_term),
and real senders never produce the term-blind wire shape.

test_ha_core_safety 28/0, no regression, no ASAN reports.
