Merge order: 1a → 1b → 1c → 1d → 2a → 2b → 3a → 3b → 3c → 4a → 4b → 4c, 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 4a: doors on the Xri backend (needs 3c). Phase 4 is split into 4a doors (VrHinge), 4b chest lid on VrHinge (replaces the interim VrChestLidToggle), 4c ladders + IsClimbing.

• New backend-neutral VrHinge (IVrHinge): grabbing the leaf turns it with the hand's angle around the hinge axis, clamped to 0-90°; after release it swings on with the last speed and stops at the limits; soft close below 5° (0.25 s); Opened/Closed events once per transition; Gothic open/close sounds once per transition (from VRVobDoor); Lock()/Unlock() (unlock gives a small push); hand > 1 m away lets go (teleport).
• Kinematic angle solving instead of HingeJoint + velocity tracking (the plan's fallback): the joint version overshot the limit by ~8°, jammed and recoiled on release. Kinematic also means the CharacterController can't push the door through its limits.
• oCMobDoor.prefab (UnityMCP): VrHinge + GothicGrabInteractable (saved disabled, enabled only by XriInteractableBridge on Xri) + XriInteractableBridge on the leaf; HVR components stay. HvrHingeBridge disables HVRPhysicsDoor on other backends.
• Lock picking: the AddForce push only applies to non-kinematic (HVR) doors.
• No HVR code copied; written from the behaviour spec in phase-4-doors-chests-ladders.md.

To test

• - Hvr: open/close doors, lock-pick a locked door; unchanged.
• - Xri: G1 old camp, grab a door leaf and pull/push → follows the hand, stops at 90°, let go while moving → swings to the limit without bouncing; close slowly → one close sound.
• - Xri: locked hut door (e.g. at (183, -2, 291)) doesn't move; pick the lock → door unlocks and opens a bit.
• - Xri: teleport while holding a door → it lets go.
• - Xri thumbstick teleport (stick forward = arc, release = teleport, grip = cancel): stairs/slopes work; red mid-air, on roofs/high walls, through bars/fences, >1 m up or >3 m down; with a torch in the right hand.
• Tested (Xri + simulator, scripted hand in the old camp): follow, clamp, release swing, soft close with one Closed, lock/unlock, the locked hut door locked by the picking script, teleport break-away.
• Not tested: Hvr backend in play (code/prefab review only), build without GOTHIC_HVR_INSTALLED, headset feel (hand angle unfiltered), a real lock-pick sequence by hand, audible sounds, two hands on one door (first hand wins).
• Known: unlike HVR, a hand or the body can't push a door without grabbing it; if the grabbing hand is destroyed while held, the leaf stays held until release; one unexplained InvalidCastException (no stack) seen once during scripted testing, not reproducible.

Doors opening works now. Also teleportation.
