shoney.arickathil 02b4b13a52 Merge master into db-residency-doctrine — and close the two half-exposed features 
The branch was 17 ahead / 25 behind with 11 conflicting files, and drifting
further: db.c had been rewritten twice on master since (group commit, then
compaction). Resolved rather than rebased so both histories stay legible.

Conflicts, and how each was settled:

- db.c: BOTH semantics kept. Master's fatal path and compaction check now sit
  behind the branch's `table_is_durable` predicate, in all three inline arms —
  a volatile table reaches neither the barrier nor the compaction check
- db-bench sample: every mode from both sides (growth, growth-verify, randread,
  replayseed, wmix) and ONE `boot` mode, which both sides had added
  independently
- db-bench.py: all six legs kept. Both sides had also grown the same
  WAL-size helper under different names; collapsed into one
- perf-targets: the branch's §5 (RAM ceiling) then master's §6/§7 — master's
  numbering had already assumed a §5 it did not have
- story frontmatter: master's `status` (the landing truth) plus the branch's
  `readiness` axis. 03 would have read `done` + `refine`, which is a
  contradiction — it was brainstormed and landed on master, so `ready`
- board: both standup blocks newest-first; master's chain rows (a superset);
  the branch's databasev2 1-2 rows with master's 3-4. Fixed a stray `|` in
  master's row 3
- baseline: master's, then REGENERATED from a full campaign — 143 metrics,
  132 checks, 0 failures with both sides' legs present

TWO HALF-EXPOSED FEATURES FIXED, because the merge rule is that master gets
no feature that is honoured in name only:

- `resident: keys` PARSED, set a .wob flag, and did nothing: rows stayed fully
  resident. A developer could declare a 120 GB table keys-resident, watch it
  compile, and be OOM-killed. The loader now REFUSES it with a message naming
  what to write instead, until tasks 5c/5d land. The compiler still parses it
  and its AST golden still passes, so the grammar work stays tested
- `durable: false` was honoured ONLY on the inline path. wo_db_exec_req had no
  guard at all, so a volatile table written from an actor on a worker shard
  would still be logged — precisely porch's session-table case, and precisely
  what iteration 2 exists to provide. All three request-path arms now carry the
  same predicate. Found by reading the merged code, not by a test: the obvious
  probe runs main() on the primary and therefore only exercises the inline path

Verified on the merged tree: wovm-test 0, woc-test 0, oop-e2e 122/0,
residency-accept 8/0, db-bench 132/0, linkcheck clean.
