Merge order: 1a → 1b → 1c → 1d → 2a → 2b → 3a → 3b → 3c, all into engine/hvr-replacement (no stacking). Each branch still contains the commits of the earlier steps, so after the earlier PR is merged the diff of this one shrinks to its own step. Plan: Docs/HVR-replacement/.

Description

Phase 2b: mobs, NPCs, melee and mouth on the Xri backend (needs 2a).

• XRSimpleInteractable + bridge on oCMob* and oCNpc: a grip means use / talk. VrInteractable.IsSelectOnly tells "use" from "hold"; VRNpc only does the grab-and-release workaround on Hvr.
• Grip on an NPC starts the dialog, again during a dialog skips the line; on a dead NPC it opens the loot panel (slots in 3c); on a mob it uses it.
• Mouth (VRMouth) on the XRI camera, so held food can be eaten.
• Helper that avoids Collider.ClosestPoint warnings on non-convex mesh colliders (used by the grab code from 2a too).

To test

• - Hvr: talk to an NPC by grabbing, use a mob; unchanged.
• - Xri: grip an NPC → dialog; grip again → line skipped; dead NPC → loot panel.
• - Xri: use a fire/wheel/bed/seat/switch by grip.
• - Xri: hold food to the mouth → eaten.
• - Xri: swing a weapon at an NPC — needs a headset: does a fast swing hit, and do slow movements cause false hits? (Thresholds are the HVR values.)
• Not tested: skipping a line while it is actually playing, beds/seats/switches, dig spots (no code change needed, reads the grabbed item per hand).
• Known: eating a held item throws MissingReferenceException (found-bugs.md).

Test on (delete if irrelevant)

• PCVR
• Mobile VR (Quest/Pico)

The raycaster to grab an object is nearly infinite. I put a ticket to update it. Apart from that: Works.
