Two fixes to the wall-endpoint reshape interaction.
selection-manager: a node:click is synthesized on R3F pointer-up, so an endpoint
handle that sits on the wall body lets the wall mesh (raycast-hit behind it from
a 3D angle) emit its own click on the same release — selecting the wall and
arming its move tool on top of the endpoint move. Ignore the body click while an
`endpoint` reshape owns the pointer. Scoped to `endpoint` so hole-edit (which
relies on node clicks to exit) is unaffected.
move-endpoint-tool: a press-drag committed on release but a tap dismissed, and
whether the tap's release ran at all raced the window pointer-up listener
mounting a tick after the handle's pointerdown ("works once, then needs a long
press"). Unify on one rule: commit only when the endpoint actually moved,
otherwise stay armed. A tap now grabs the endpoint (it follows the cursor; the
next click after a move commits) exactly like a press-drag — both engage
identically. Drops the now-dead hasDraggedRef.
