perf(core): FloatingIslands whole view 16.7 s -> 7.4 s (L51); research R20

Browse Source 
Measured first: 45% of FI tiles are all-air, yet FloatingIslandFieldV1 returned unknown for any box near
an island AABB (25,536 unknown boxes, 0 tile skips). Conservative ranges for island bodies, root lobes,
buttresses, connectors, surface detail and smooth-min budgets now let the shared box classifier prove FI
air/solid (216 tile skips; 28.6 M audited samples, 0 violations). The X8 path reuses its FI preflight
samples. LOD7-8 far-shell and column work is skipped outside per-tile island/connector influence bounds
(farHorizonVersion 4 -> 5). FI 16.74 -> 7.36 s (-56%), FI moving entering-tile p50 halved; SW unchanged.
Peer determinism (Clang/GCC W1/W8/W12, random cameras) PASS; fast/medium/full PASS.
Research R20: world-type catalogue and dreamcore/liminal concepts (revised after a deepening pass).
