bb7b899bfe fix(physics): TS-23 - plumb real PK/PKLite/Impenetrable mover flags
Campaign P Slice P3 item 3. The wire parse (CreateObject's
PublicWeenieDesc._bitfield), the decode (EntityCollisionFlagsExt.
FromPwdBitfield), the per-GUID storage (ClientObjectTable.
PublicWeenieBitfield), and the exemption logic (CollisionExemption.
ShouldSkip) all already existed and were already correct -- every
mover-flags call site just fed a GUID-prefix IsPlayer heuristic instead
of the real per-entity PK/PKLite/Impenetrable state (retail
OBJECTINFO::init 0x0050cf30 state |= 0x80/0x800/0x1000).

Port:
- EntityCollisionFlagsExt.ToMoverState translates the decoded PWD
  bit-space into the ObjectInfoState bit-space FindObjCollisions
  actually reads -- two different numberings that must not be
  confused. Deliberately does not translate IsPlayer (every call site
  already derives that correctly from its own GUID heuristic per
  #184 Slice 2b).
- EntityCollisionFlagsExt.ResolveMoverPvpState is the one shared
  ClientObjectTable-backed lookup (guid -> ObjectInfoState), replacing
  what would otherwise have been three separate inline copies across
  GameWindow/LivePresentationComposition/RemoteTeleportController.
- Threaded as a new optional moverPvpState parameter through
  RuntimeRemotePhysicsUpdater.Tick/TickHidden and
  RuntimeOrdinaryPhysicsUpdater.TryBegin (default None preserves every
  pre-P3 caller unchanged), and as PlayerMovementController.OwnPvpFlags
  for the local player's own two resolve call sites.
- TS-23 section 12b: PlayerWeenie.JumpStaminaCost's pk parameter now
  reads the real PlayerKillerStatus(0x86)/LastPkAttackTimestamp(0x91)
  pair against retail's 20-second recency window
  (pkStatus in {4, 0x40} && (timestamp + 20.0) >= now), replacing the
  P1 hardcoded false. RuntimeMovementSkillState/Snapshot and
  LiveSessionEventRouter.RecomputePvpStatus push both the PWD bitfield
  and the PlayerKillerStatus pair reactively, riding the SAME
  ClientObject event triggers RecomputeBurden already uses.
- A conformance test caught a genuine precision bug in the first
  PK-timer clock choice: DateTimeOffset.UtcNow's Unix-epoch seconds
  (~1.7 billion) loses ~128 seconds of precision in a 32-bit float,
  silently swallowing the entire 20-second window. Switched to
  Environment.TickCount64 (small, monotonic magnitude) -- also the more
  retail-plausible basis, since LastPkAttackTimestamp is itself a wire
  PropertyFloat and retail's Timer::cur_time is almost certainly a
  process/session-relative counter for the same precision reason, not
  an absolute epoch.

Non-PK invariant (the acceptance criterion): an entity with no
ClientObjectTable row, or a row whose PublicWeenieBitfield is null or
0, resolves to ObjectInfoState.None -- a no-op OR into moverFlags,
bit-identical to every pre-P3 caller's hardcoded value. A dedicated
test drives two real ClientObjectTable rows through
CollisionExemption.ShouldSkip and confirms PK-vs-PK collides while
PK-vs-non-PK and non-PK-vs-non-PK both stay exempt (walk through).

Register: TS-23 retired (both the collision-flags and PK-timer halves);
the stale "M2 combat must land TS-23" phase-gate note removed.

dotnet build + dotnet test (Core.Tests 4008/2 skip, Runtime.Tests
425/0, App.Tests 3968/3 skip, complete solution build) all green.

dae5b1ea68 fix(physics): TS-46 - seed the sweep from the Setup's own sphere list
Campaign P Slice P3 item 1. Retail CPhysicsObj::transition (0x00512dc0)
seeds the collision sweep from CPartArray::GetSphere (the Setup's own
<=2-sphere list, each origin+radius scaled by m_scale) via
SPHEREPATH::init_sphere (0x0050c670) -- not from a symmetric two-scalar
(radius, height) capsule reconstruction. The human Setup 0x02000001's
authored spheres are (0,0,0.475) r=.48 and (0,0,1.350) r=.48; the old
reconstruction from (0.48, 1.835) produced (0,0,0.48) + (0,0,1.355), a
5 mm head-center offset the TS-46 register row documented as a residual.

Port:
- SpherePath.InitPath gains a sphere-list overload (ImmutableArray<
  FlatCollisionSphere>, scale) sharing a new InitPathCore with the
  existing (radius, height) overload, which is now the degenerate
  2-scalar case of the same code -- byte-for-byte unchanged, so every
  captured-fixture replay (CellarUpTrajectoryReplayTests,
  DoorBugTrajectoryReplayTests, CellarLipWedgeTests) keeps passing
  unmodified.
- PhysicsEngine.ResolveWithTransition gains optional sphereList/
  sphereScale parameters; empty/default preserves the legacy scalar
  path for every pre-existing caller.
- LiveEntityMotionRuntimeController.GetSetupMoverShape is a new sibling
  of GetSetupCylinder (left untouched) that resolves the Setup's own
  sphere list plus Setup-derived step-up/step-down
  (CPartArray::GetStepUpHeight/GetStepDownHeight, 0x005180d0/0x005180f0,
  x ObjScale, 0.4 m fallback matching the pre-existing literal).
- Threaded through PlayerMovementController (both resolve call sites,
  new SphereList property set by PlayerModeController.ApplyStepHeights
  and the Headless world projection), RuntimeRemotePhysicsUpdater
  (Tick + TickHidden), and RuntimeOrdinaryPhysicsUpdater.TryBegin.
  Remote/ordinary step heights are now Setup-derived instead of a
  hardcoded 0.4f literal. Projectile and camera-probe sweeps are
  untouched (already single-sphere-exact).
- PlayerModeController.ApplyStepHeights also now applies the x ObjScale
  multiply to the player's own step heights (previously only the
  remote/ordinary paths did), closing an adjacent gap the P3 research
  flagged.

Ts46SphereListConformanceTests proves the sphere-list overload sees the
exact dat spheres (not the reconstruction), that the scalar overload is
unchanged, and that ResolveWithTransition's sphereList parameter
actually drives the sweep (a decoy-scalar control pair using a
head-height obstacle sphere).

Register: TS-46 retired (both residuals it named are closed); header
count corrected to 40 active TS rows.

dotnet build + dotnet test (Core.Tests 3991/2 skip, Runtime.Tests
425/0, App.Tests 3968/3 skip, complete solution build) all green.

7e6033d0ad refactor(runtime): own per-session physics simulation
Move the sole PhysicsEngine, production cache, collision admissions, canonical bodies and hosts, remote components, ordinary/remote worksets, simulation, cell commits, and shadow synchronization under RuntimeEntityObjectLifetime. Keep App as the prepared-asset, animation-input, and render-projection adapter while preserving the named-retail update and collision order.

Add exact-incarnation, object-clock, callback-reentrancy, GUID-reuse, two-runtime isolation, source ownership, collision publication, and graphical projection coverage. Release build and the complete 8,588-test solution pass.
