Adds the Raft Apply-Ordering & Hook Decoupling roadmap phase: canonical
pre-hooks -> raft commit -> apply -> notify ordering, with the raft protocol
step lifted out of the notification hook fan-out (root of the bug-795/828/
851/1060 divergence family). Decision: apply-after-commit via a single
shared apply_committed_entry() seam reused by online apply and restart
replay.
- raft-drive-async: full spec docs (brief/requirements/research/design)
committed alongside its already-tracked tasks.md; async-drive prerequisite
for the apply-decoupling work, sequenced to start first (threatens
failover liveness today).
- raft-apply-decoupling: new spec (brief + facts-in-raft.md) covering the
apply seam and the facts (WAL_MODE_RETAIN) apply-timing question (open
decision D1).
- job-array-single-wal-record: promoted from backlog to a tracked spec,
sequenced after raft-apply-decoupling.
- ha-consistency-invariants: add criterion 2.9 (Facts-Apply invariant),
documenting the current on-receipt fact-reaction deviation this family
will reconcile.
- raft-commit-safety / raft-log-replication: reconcile spec.json phase to
"implemented" (both were mislabeled tasks-generated despite full 18/18
and 24/24 task completion + raft_sim GO).
