feat(R1-P5): AnimationSequencer rehosted on the verbatim CSequence core

Browse source

The adapter keeps its full public surface (every consumer compiles
unchanged) while the internals move to Motion.CSequence:

DELETED (legacy invented mechanisms, per the R1 gap map + Phase R
mandate): the AnimNode class + adapter queue/_currNode/_firstCyclic/
_framePosition, the ACE-fabricated FrameEpsilon boundary math, the
safety=64 advance cap, ClearCyclicTail surgery, the stale-head
_currNode relocation block, per-node IsLooping/Velocity/Omega, the
adapter-side AdvanceToNextAnimation/ApplyPosFrame/ExecuteHooks, the
per-node !IsLooping AnimationDone gate (now the core's list-structure
head != first_cyclic gate, G5).

REHOSTED: SetCycle rebuild = RemoveCyclicAnims (+ClearAnimations for
K-fix18) + retail add_motion appends (framerate-only AnimData scaling,
G10 loop membership: the LAST appended node is the cyclic tail) + Fix B
via RemoveAllLinkAnimations (the core's snap-forward IS Fix B's
behavior); Advance = core.Update(dt, null) with hooks flowing through
an IAnimHookQueue adapter into the existing ConsumePendingHooks drain;
fast path = core.MultiplyCyclicAnimationFramerate + the adapter-level
velocity rescale (R2's change_cycle_speed composite stand-in, G13).
Kept byte-identical: adjust_motion remap, GetLink + stop-anim fallback,
K-fix18, velocity synthesis, SlerpRetailClient, the #61 render-side
clamp, SCFAST/SCFULL diagnostics.

Tests: 2 updated with decomp citations — the reverse-start boundary now
pins retail's bare-int HighFrame+1 (0x00525c80, no epsilon, G1); the
root-motion accumulation test pins the inert-stub state pending P6's
Frame wiring (G7). All 44 sequencer tests + the 56 core tests + full
suite green (3346).

Implemented by a dedicated agent against the P5 spec; diff + tests
reviewed, suite re-verified before commit.
