[all] Fix compilation warnings

[hugtalbot]

Massively fix warnings for the pleasure

What was fixed

• Unused parameters
• Sign-compare
• Deprecated barycentric API for you @epernod

Some points worth attention

-. BoxROI.inl was a genuine out-of-bounds read, not just a warning. isPointInAlignedBox looped to DataTypes::spatial_dimensions and indexed box[i+3], so for Vec6Types it read indices 6/7/8 of a Vec6. An axis-aligned box packed as (min₃, max₃) can't describe more than 3 dimensions, so I capped the loop at 3 and documented that higher dimensions are ignored.

• CCDTightInclusionIntersection.cpp:187 — the bool from ticcd::edgeEdgeCCD is discarded and a contact is created unconditionally. That looks like a real bug, but acting on it changes collision behaviour, so I only silenced it ([[maybe_unused]] + a comment noting the call is kept for its toi/outputTolerance outputs). Your call whether it should early-return.
