VIOLET V2c: synthetic intent scripts + ExecStormHarness + 9-scenario matrix

synthetic_intents.py: seeded IntentScriptSpec -> CycleSpec scripts
(script_hash + outcomes_hash determinism, V0 discipline); per-scenario
router ExecConfig constructed directly (no env mutation); cycle executor
runs full ENTER->terminal->flatten lifecycles with per-scenario terminal
predicates and cycle-end invariants (working registry empty, driver
drained, slot flat).

exec_harness.py: composition root — production bundle (MOCK, injected
ScriptedVenue), ExecDeadlineDriver ports wired, pump = venue.reconcile()
-> kernel + driver.on_fill forwarding (the production seam), gate report
via the ExecGateReport schema, archive next to V0 reports.

scripted_venue.py amendment: MARKET orders never rest (venue realism —
directives are keyed by trade_id and the R1 MARKET fallback shares the
position's trade_id).

Matrix green through the REAL kernel at 100ms TTL: immediate fill,
rest-then-fill (deadline cancelled), fill-races-cancel (no retry),
rest-expire-retry (-r1 opens), retry-exhaust skip|market, exit-expire ->
MARKET same trade_id, post-only reject, cancel-reject (no strand). Two
runs same seed -> identical outcomes_hash. Router 77 green; shared clean.
