Added

- Melee weapon part detection from the actual blade. In swing motions (e.g. Better Combat), the

  held weapon's rendered model is captured to recover the hilt->tip segment, and the first body

  part that segment touches is the part that's hit. No per-weapon hardcoding: the blade axis and

  length come from the principal axis (PCA) of the model vertices, so swords, axes, spears and

  modded weapons each use their own tip (display transform and centering replicated exactly from

  vanilla rendering). Hits follow the weapon you see, not the look ray.

- Unified melee judgment for humanoids and non-humanoids. Both resolve the first-contact part from

  the same weapon segment (biped OBB for humanoids, captured parts for others); the client-resolved

  part is consumed by the server. The old look-ray path is used only as a fallback when the weapon

  doesn't reach.

Changed

- The (unscoped) melee part stash now keeps the latest value — as a swing progresses the tip moves

  across parts, so the frame just before damage is used (bullet-scoped hits still keep the first

  real part).
