Leonid PershinandClaude Fable 5 e06f24a319 Parallel rendering pipeline, ring vertex buffer, phase timings
Five optimizations measured on the 100k-entity stress scene (Release,
vsync off): 103 FPS baseline -> 297 FPS.

- Sprite submission and vertex building run on all cores above
  Renderer2DOptions.ParallelThreshold (default 8192). Work is sliced
  into 4096-entity segments: a Friflo chunk holds a whole archetype,
  so per-chunk parallelism degenerates to one thread. Segments merge
  in deterministic order, preserving radix sort stability.
- Vertex buffer is ring-written with SetDataOptions.NoOverwrite
  (GPU buffer 2x frame size); Discard only on wrap-around.
- Texture2DRegion precomputes UVs - four float divisions per sprite
  per frame removed.
- Renderer2D exposes per-phase timings (submit/sort/build/upload/draw),
  shown in the sample HUD - all further optimization is data-driven.
- Sample BounceSystem parallelized the same segmented way.

Leonid PershinandClaude Fable 5 af319d1276 Add MrGameEng.UI module integrating Myra
scene.UseUI() creates a per-scene Myra Desktop and registers
UiRenderSystem last in the draw phase (UI on top, window pixels).
GameHost now exposes itself as a Game service (Myra needs the instance;
useful for games too). Myra was picked over Gum/ImGui for the
FontStashSharp ecosystem fit, pipeline-free assets and maturity; its
internal SpriteBatch use is a documented exception to the engine rule.

Sample: on-screen HUD replaces window-title-only stats — live FPS label,
music volume slider and scene-switch buttons on both scenes.

Leonid PershinandClaude Fable 5 2b7d4c4fef Add scene transitions (fade, wipe) to SceneManager
Switch(scene, transition) covers the old scene, swaps at full coverage
(hiding slow OnLoad), then reveals the new one. Built-in Fade and Wipe
transitions draw through TransitionRenderer (BasicEffect quad, no
SpriteBatch); custom transitions subclass Transition. Runs on unscaled
time so it works while gameplay is paused; Switch during a transition
replaces the pending target.

Sample: Tab now fades into the stress scene and wipes back.
