feat(mod): Stage 2 — frame budget + profiler + -Dlovisual.opt.* overrides
Per mod/docs/optimize-layer-design.md Stage 2. Engine-side state holders (render/engine/optimize/profile/): - FrameBudget: Mode enum (OFF/SOFT/AGGRESSIVE) + target FPS + per-subsystem caps (entity LOD distance², particle near/mid², spawner distance, trail max points + step). Scale 1.0 / 0.9 / 0.6 per mode. NOT auto-degradation — the user picks the mode explicitly; Phase 9 rule stands. - FrameProfiler: per-section EMA timings (entities/particles/HUD/effects/text), try-with-resources Section API, 2 s idle decay, frame-time tracking. - OptimizePropertyBridge: -Dlovisual.opt.* system-property overrides. 10 properties (entity_lod, particle_lod, spawner_cull, spawner_tick_cache, block_entity_cache, prepared_text_cache, micro_opts, entity_lod_distance, spawner_distance, budget_mode, target_fps) + all=false to disable everything. Mirrors ZakoOpt's ZakoOptConfig.refresh() shape. Module wiring: - Optimize.java: extended with budget_mode (enum), target_fps (15..360), show_profiler toggles. pushState() now resolves the property bridge and pushes FrameBudget + OptimizeToggles snapshots together. Tests (JUnit 5): 22 new tests — FrameBudgetTest (8), FrameProfilerTest (7), OptimizePropertyBridgeTest (12). Total suite: 849 tests, 0 failures. Note: OptimizeDebugHudMixin (the F3 overlay) is committed in a separate patch alongside the Stage 3 mixins because it depends on the RenderBackendOps GL/Vulkan strategy interface for the property-bridge status line.
