Erik 6c7e3ef1ab feat(physics): D4+W1 — entry-restrictions register row + named PvP/missile dispatch terms
Part A (D4): CObjCell::check_entry_restrictions (pc:309576) gate is omitted from
FindEnvCollisions. Investigation confirmed the gate requires restriction_obj (per-cell
access-lock entity id) + weenie-object-table dispatch (CanMoveInto / CanBypassMoveRestrictions)
— neither exist in acdream. CellPhysics has no restriction_obj field; DatReaderWriter
models no per-cell access locks. Gap is inert in all dev content (ACE starter area has
no access-locked env cells). Documented as AP-50 in the retail divergence register.

Part B (W1): Replace the hardcoded-false smell in BspOnlyDispatch with named internal
helpers PvpExempt() and MissileIgnore() that return false with retail oracle citations
(pc:276808-276841 and pc:274385 respectively). BspOnlyDispatch now folds all three
terms in retail's exact predicate structure. Behavior is byte-identical in M1.5 scope
(both stubs false ⇒ reduces to HAS_PHYSICS_BSP_PS check alone, same as before).
A6.P7 door dispatch unchanged.

Tests: 3 new guard tests in A6P7DispatchRulesTests — W1_PvpExempt_ReturnsFalseInM15Scope,
W1_MissileIgnore_ReturnsFalseInM15Scope, W1_BspOnlyDispatch_DoorStateStillDispatchesBspOnly.
Suite: 1590 pass / 0 fail / 2 skip (was 1587 + 3 = 1590).
