Adds narrow_channel.dsn: a keepout wall with a narrow gap positioned off the routing grid, so no grid cell centre falls inside the gap's free centreline. The exact/grid track drops the net (cell quantization can't fit a centreline in the channel); the continuous room track routes it. This is the headline result that continuous free-space beats the grid. Tests: the room router's output is DRC-clean (exact has_violation is None) on simple/crossing/kicad/narrow_channel; it connects simple/crossing (with a via) and all four multi-pin KiCad nets; traces are orthogonal and end on pads; and the continuity contrast asserts exact routes 0 while rooms routes 1, both clean. Oracle-gated connectivity parity on simple/crossing.
