fix(h3d-carve-15): resolve Creed r1 F1/F2/F3 + camera import + smoke tests

F1: return { update, _prewarmStatic, _prewarmChart } from createRenderer;
    screen.js destructures all three (callers at :7377/:7461 were getting undefined).

F2: _applyNoteCamTargets read cameraLockLow/cameraLockZoom as free variables;
    replaced with getCameraLockLow() / getCameraLockZoom() getter calls.

F3: add dZ, renderOrderForLayerAtZ to geometry.js import; DI TS, S_BASE,
    FRET_LABEL_GOLD_HEX, FRET_LABEL_IDLE_HEX as shorthands from screen.js.

Camera import fix: camera.js only exports createCamera; remove the broken
    import of lookaheadBootstrapTime/ComputeFretBounds/TargetWorldX from
    camera.js (caused SyntaxError on module load); DI them as shorthands
    from screen.js createCamera() destructure at line 6755.

DI count: 177 → 184 (+7 shorthands).

Tests: 6 new execution-readiness guards (17-22) in highway_3d_renderer.test.js,
    each RED at 7180eff and GREEN at this tip. Suite 1402/1403 (pre-existing #46).

ESLint gate: Creed F1/F2/F3 names cleared; 160 remaining no-undef identifiers
    documented in hive/plans/h3d-cut15-creed-fix.md (categories B-G: deferred
    screen.js consts/fn-refs and renderer-internal closure state — carve-15b).
