Add Future Pinball table import support

[freezy]

Summary

• add bounded readers for Future Pinball FPT, FPL, and FPM compound files
• extract a deterministic, lossless source bundle containing every stream plus images, sounds, music, DMD data, scripts, models, lists, linked-library resources, and opaque records
• decode MilkShape models and generate supported procedural table meshes
• convert Future Pinball materials and textures into reusable Unity assets
• create VPE-native playfield and primitive colliders; no Unity/PhysX colliders are used
• add a dedicated Unity import wizard, provenance components, import reports, and a recreation backlog for unsupported behavior
• update OpenMcdf to 3.1.4 and migrate the existing compound-storage callers

Collision mapping

• playfield dimensions, glass, bounds, and slope use PlayfieldColliderComponent
• procedural and per-polygon model collision use PrimitiveColliderComponent
• boxes map exactly to triangle meshes
• cylinders, spheres, and tapered capsule/flipper shapes are tessellated approximations
• invalid, unknown, disabled, or otherwise unsupported collision records remain in the lossless bundle and are reported in the recreation backlog

Validation

• 44 Future Pinball tests pass against five locked real-table fixtures
• VisualPinball.Engine.sln builds successfully
• the FPT Unity runtime/editor sources compile against the actual Unity managed and project assemblies
• each implementation phase, including the final VPE-native collider conversion, was independently reviewed and greenlit by Claude Opus before commit

Current limitations

• Future Pinball scripts are preserved but not executed
• numeric Future Pinball collider-event dispatch is not recreated
• moving mechanisms and other runtime behavior still require semantic mapping to their native VPE components
• curved analytic collision shapes are tessellated rather than represented analytically
• physics-material coefficients are not yet translated for numerical parity with Future Pinball
• a live Unity import/play-mode smoke test is pending because the current local HDRP project has unrelated pre-existing Magnet/BitField64 and missing MagnetDetectionWindow compile errors

Fixture setup

Set VPE_FPT_FIXTURES to the directory containing the locked Future Pinball table corpus before running the real-table tests.

Greptile Summary

This PR adds Future Pinball table import support. The main changes are:

• Bounded readers and extractors for FPT, FPL, and FPM compound files.
• Source bundle preservation for streams, assets, scripts, models, and opaque records.
• MilkShape model decoding and procedural table mesh generation.
• Unity import UI, reports, provenance components, and VPE-native collider creation.
• OpenMcdf update and compound-storage caller migration.

Confidence Score: 5/5

This looks safe to merge.

• No blocking issues found in the changed code.
• The latest surface-placement fix skips unresolved support cases instead of placing objects at a guessed height.
• Texture lookup keeps exact names ahead of aliases and avoids using ambiguous aliases.
