feat(rope): reel tether length to track player distance

Browse Source 
Rope length was baked once at load, so it sagged when players closed in
and the pin joints fought when they separated.

Total length now eases toward clamp(gap * (1 + slack), min, max) at
reel_speed. Joint3D only derives anchors from node transforms when the
joint is configured on tree entry, so anchors are pushed straight to
PhysicsServer3D.pin_joint_set_local_a/_b after resizing the capsules.

Also instances the rope in 3dlevel and solves the spawn arc's bow height
from the same target length, so the rope no longer lurches on frame one.
