Ryan Malloy a06adbee13 Add shove-in-rooms and gate-placement fixtures and tests
rooms_shove_channel is the headline density win: a sealed NET_A wall
leaves no top<->bottom door, so plain room routing drops NET_C; with
shove=True NET_A is nudged aside and both nets route, DRC-clean and
deterministic. rooms_wide_door seats two nets through one wide gap at
distinct projected gate points with no shove.

Cover the occupancy-aware projection math directly, assert the four
foundation fixtures stay byte-identical under shove=True (shoves==0), and
extend the room DRC-clean parametrize with both new fixtures.
