feat(physics): integrate live projectile runtime

Browse source 
Attach the retail projectile driver to canonical LiveEntityRecord ownership, sharing one PhysicsBody and full-cell identity with RemoteMotion regardless of creation order. Apply timestamp-gated state, vector, and position corrections in place, preserve active ordinary-body behavior when Missile clears, and keep renderer, effects, shadows, and spatial buckets synchronized across loaded/pending transitions.

Validate malformed packets before canonical timestamp mutation, validate adopted bodies from their current frame rather than stale CreateObject data, serialize late Setup resolution with streaming DAT reads, and preserve classification across clock anomalies. Retain shadow registrations through temporary leave-world residence while logical teardown remains generation-scoped.

Add 31 App lifecycle/adversarial tests plus Core shadow suspension coverage, and synchronize the retail pseudocode, architecture, milestones, roadmap, and durable physics memory.

TS-11, and TS-12 are retired; AP-83/AP-91 remain dormant. Step 7 attaches
that primitive to the canonical `LiveEntityRecord`: arrows, bolts, and spell
missiles share one body and one renderer identity across prediction,
authoritative State/Vector/Position/Movement corrections, full-cell
rebucketing, pending-landblock residence, delete, session reset, and GUID
reuse. MovementManager presentation shares the same body and the canonical
live-record cell regardless of which component was created first;
pending/leave-world shadows retain their registration for exact re-entry even
if Missile classification changes while pending; static missile effect
roots follow every predicted frame, and materialized rehydration never uses a
stale spawn cell. No impact, damage, effect, or delete event is synthesized
client-side. The remaining steps port
Hidden/UnHide portal presentation and run final hardening/visual gates.
