docs(archreview): round-2 re-review (2026-07-12) + 8 fix plans (86 tasks)

Re-ran all 8 domain reviews at HEAD 8c888f13 against the b910f5eb baseline:
every round-1 finding source-verified (168 fixed, 0 regressions, 0 false
claims); 56 new findings (1 Critical / 4 High / 15 Medium / 36 Low),
concentrated in post-baseline code (anti-entropy resync, KPI rollup
backfill, live alarm stream) and seams the fixes exposed.

Headliners: S&F resync predicate inversion can wipe the delivering node's
buffer (02-N1 Critical); resync snapshot exceeds the Akka remoting frame
size (02-N2); failover drill kills the one node keep-oldest can't survive
(01-N1); unbounded rollup backfill per failover (04-R1); live production
API key in untracked test.txt (08-NF1).

Adds PLAN-R2-01..08 + .tasks.json manifests and the Round-2 board,
P0 list, cross-plan mutexes, and wave order in 00-MASTER-TRACKER.
