feat(R3-W3): verbatim jump family — charge gates, jump_is_allowed chain, epsilon fixes; StandingLongJump misattribution retired (closes J5, J6, J7-interp-side, J16-epsilons)

JumpChargeIsAllowed 0x00527a50 (CanJump→0x49 before posture; Fallen +
Crouch..Sleeping→0x48), ChargeJump 0x005281c0 — now the ONLY place
standing_longjump arms (grounded Contact+OnWalkable + forward Ready +
no sidestep/turn, raw @305453-305466); the S2a-flagged side effect
inside contact_allows_move is DELETED (J6) with regression pins that
contact checks never touch the flag (the funnel's StandingLongJump
branch is local-player scope; the controller wires ChargeJump in W4/W6
— remotes never charge client-side, no interim regression).

jump_is_allowed 0x005282b0 full chain replaces the 15-line
approximation: IsFullyConstrained→0x47 (new PhysicsBody stub, TS-35)
BEFORE the pending-head peek (A2 ordering, pinned); head peek fires
whenever the queue is non-empty (no ACE Count>1 gate; nonzero
jump_error_code short-circuits the whole chain — test proves
JumpStaminaCost is never consulted); retail entry shape verbatim
(non-creature-weenie and gravity-off skip the ground gate; null
physics obj → 0x24 NOT 8 per A10); charge → MotionAllowsJump(fwd)
double-check → JumpStaminaCost gate (new IWeenieObject member,
always-affordable PlayerWeenie stub — TS-5 extended).

GetJumpVZ/GetLeaveGroundVelocity: epsilon corrected to retail's
0.000199999995f (was 0.001 — regression-pinned at extent 0.0005);
A5 shape (clamp 1.0, weenie-null 10.0f); A6 momentum fallback fires
only when ALL THREE components are sub-epsilon and overwrites all
three with global→local(m_velocityVector).

Jump 0x00528780: InterruptCurrentMovement no-op seam (TS-36, →R4
cancel_moveto), fires unconditionally; standing_longjump cleared ONLY
on failure (success keeps it — pinned). IWeenieObject.IsThePlayer()
(PlayerWeenie true) lands for W4's A3 dispatch.

51 new tests + 1 re-pin; superseded pre-W3 jump tests removed. Full
suite: 3,623 passed. Registers: TS-5 extended, TS-35/36/37 added.

Implemented by a dedicated agent against the W0-pinned spec; arming
gates + entry shape verified against the quoted raw text.
