Collapse the two tunnel buttons into a single Tunnel button whose ghost resolves between Tunnel Entry and Tunnel Exit based on the hovered position, with a green connection preview. - Add pure core helper TunnelCompletion (firstTunnelFacing + resolveTunnelCompletion): the entry/exit completion scans and the sub-tile cursor tie-break, unit-tested in TunnelCompletionTest. - Dedup BeltSystem::reevaluateTunnelPairing onto firstTunnelFacing so the pairing scan rule lives in one place. - GameWorldView: resolve the ghost type on hover/rotate (matching built tunnels and construction sites), place the resolved type (drop the old auto-switch), and draw the matched partner + between-tiles in green. Hotkey 3 = Tunnel, 4 unused. - BuildButtonGrid: one "Tunnel" button; tunnel_exit stays player-placeable so blueprints and cost totals still account for exits. - Add the green tunnel_preview overlay color (VisualsConfig/Loader/toml).
