audit(movement.keyboard.motion): close Paralysis/Faint/Sleep gate as false positive

Investigated the prior round's flagged gap ("CanAct()'s Paralysis/Faint/Sleep
movement doors not wired into net_play.gd") via exhaustive reachability
tracing of the 40250 reference source. All three resolve to non-gaps:

- Paralysis: its only setter (__Shaman_SetParalysis, InstanceBaseEffect.cpp:821)
  has zero callers anywhere in the reachable source -- dead code, never true
  in live gameplay.
- Sleep: the AFFECT_SLEEP case in SetAffect() is commented out; the only live
  setter is the AFFECT_STUN case (SetSleep(), InstanceBaseEffect.cpp:932-933),
  i.e. IsSleep() is just an alias for AFFECT_STUN -- already covered by the
  existing `stunned` field and _can_process_network_state()'s dead/stunned/
  knock_down gate.
- Faint: only setter is chrFaintTest(), a debug-only Python binding operating
  on GetSelectedInstancePtr(); unverifiable from the available 40250 checkout
  (no root/ UI scripts) -- evidence-blocked, left unresolved per the skill's
  reachability rule.

Byproduct finding while tracing IsStun(): main-character GC_STUN routes to
Die() in the reference (RecvStunPacket), not Stun(); verified this causes no
movement.keyboard.motion discrepancy since CanAct() blocks movement equally
on IsDead()/IsStun() and the current client already blocks movement equally
on dead/stunned. The Die()-vs-Stun() distinction only affects death-system
semantics, already tracked under combat.affect-status.md (Remaining #2, rows
63/67) -- not duplicated here.

No implementation code changed. Removed the resolved item from manifest.json
and movement.keyboard-motion.md's Remaining list; documented full evidence
in the contract doc and remediation roadmap. Contract stays PARTIAL
(AccumulationMovement root-motion, OnMove/OnMoving event-source parity,
sync/hit/death/warp gate stacking, and real-model bone-flip test remain open
for future rounds).
