fix(meta): replay-by-key + single failIntent on refusal (PR #106 criticals; importants deferred)

FIX 1 (cascade-risk critical): dispatch's replay short-circuit matched on
intent_id alone, ORDER BY executed_at DESC LIMIT 1. Any intent that ever
produced a terminal cc_actions_log row would short-circuit forever, no
matter what idempotency_key the new attempt computed — making per-attempt
retries unreachable. Reordered to (a) compute attempt+key first, then
(b) lookup by (intent_id, idempotency_key) which is the canonical
per-attempt invariant the partial unique index backs.

FIX 2 (cascade-risk critical): both refusal paths in dispatch wrote audit
+ called failIntent, then returned without `replayed: true`, so
executeIntent's `!result.replayed` guard called failIntent a SECOND time.
The DB no-ops the second call (status guard), but the semantic is wrong
and the error_message could be clobbered on adjacent paths. Both refusal
returns now set replayed:true; executeIntent's guard skips correctly.

Updated existing executor.spec.ts: the second-invocation block encoded
the pre-fix bug (asserted same-intent re-call replays). Under the new
contract, a second executeIntent against the same intent is a new
attempt with a new key → executor re-runs (idempotent for
update-obligation-status), audit count goes 1→2, attempt sequence [1,2].

Added tests/meta/executor-pr106-criticals.spec.ts:
- FIX 1 regression: hand-insert a terminal row with a sentinel key
  ('a'*64) for an intent, then executeIntent — key mismatch must NOT
  short-circuit, executor must run, obligation must transition.
- FIX 2 regression: stale snapshot + unroutable CHITTYTRUST_URL (RFC 5737
  192.0.2.1) forces real fetch failure → sovereignty 'blocked' → refusal
  path. Asserts result.replayed === true (the canonical FIX 2 signal)
  and exactly one sovereignty_refusal audit row.

No mocks. Real Neon only — skipped without DATABASE_URL.

Validated the FIX 1 SELECT shape against a real Neon branch
(cool-bar-13270800 / pr-106-criticals-validation, since deleted): the
key-matched query returned the seeded row for matching key and empty
for non-matching key.

Deferred to follow-up PR (intentionally out of scope here):
  - FIX 3: race-safety on concurrent dispatchers (writeAuditRowOrReplay)
  - FIX 4: schema predicate gap (status enum vs literal IN-clause)
  - FIX 5: cold-start registry import on direct dispatch entry
