Replace REQ-BLD-TUNNEL-AUTO-SWITCH with REQ-BLD-TUNNEL-MODE: one Tunnel
button whose ghost defaults to Tunnel Entry and auto-switches to Tunnel
Exit based on which end the hovered position would complete (via
REQ-BLD-TUNNEL-PAIR), with a green connection preview and sub-tile
mouse-proximity tie-break. Update REQ-UI-HOTKEYS (3 = Tunnel, 4 unused)
and REQ-UI-BUILD-GRID (shared Tunnel button).

Extend REQ-BLD-BELT-DRAG: dragging a belt onto a building/construction site
snaps the end tile to the input-capable adjacent tile closest to the cursor
(geometrically closest, always), with that tile's belt pointing into the
target across the shared input edge, overriding the final-tile orientation.

REQ-BLD-BELT-DRAG now states that rotating the belt with R/Shift+R while a
drag is in progress re-picks the path's primary axis immediately and
re-derives the path, rather than waiting for the next cursor movement.

Deferred, L-shaped drag placement for belts: ghosts along the path,
placement on mouse release, auto-oriented tiles, right-click cancels
the drag without exiting belt build mode. Occupied belt cells are
re-oriented in place; unaffordable tiles show no ghost.
