Josh Creek 7b150ef72e feat(multiplayer): task 2.8 net_sim.gd, close out Phase 2
New NetSim autoload: seeded, CLI-driven (--net-sim-latency/-jitter/-loss/-dup)
latency/jitter/loss/duplicate decorator, a true no-op passthrough unless a
flag is set. Wraps MatchSim.send_input/send_snapshot per the design doc's
scope, plus NetworkManager's ping/pong so the already-tested RTT/clock
measurement becomes the acceptance signal for "raises observed RTT" without
waiting on Phase 3's per-peer snapshot echo.

Two real bugs found while building and verifying this against Phase 2's own
milestone gate (a real match under --net-sim-latency 80 --net-sim-jitter
20, not just LAN): a timestamp captured inside a delayed RPC closure
silently ate that side's own added delay out of the round-trip
measurement instead of adding to it; and a delayed send whose target
disconnected (or whose own process had already shut down) during the hold
threw RPC errors, since the existing get_peers() filtering only checked
validity at schedule time. Fixed by capturing timestamps before handing
off to NetSim, and by having NetSim re-validate the target at fire time.

Phase 2's milestone gate now passes for real: a full 1v1 under simulated
80ms latency / 20ms jitter still shows clean server-authoritative
movement and zero RPC errors. Full Phase 1 + Phase 2 regression suite
re-verified clean with NetSim present but inactive.

; Task 0.17c: kept fixed at "viewport" + 1080p rather than moved to
; "disabled", deliberately. A player on a 1440p/4K display cannot render
; native this way, and a 1080p player cannot render lower than 1080p through
; window scaling alone — but task 0.17b's Viewport.scaling_3d_scale already
; covers "render lower than the window" independently of stretch mode (it
; scales the 3D viewport's own internal resolution before this blit, not the
; window itself), and task 0.15b found an unexplained ~6% non-uniform width
; scaling on this project's one tested (Mac/Retina) machine — see
; multiplayer-todo.md §5.5.1 — that needs understanding before stretch mode
; is touched, not blindly carried into a resolution-dependent change.

; brief pre-autoload window and if VideoSettings ever fails to load.
