[Feature]: [P3] Re-key the lobby-distance pressure on elevator reach and transfer depth, not raw floor count

Follow-up from the #435 recalibration (agent panel + red-team deliberation, 2026-07-16).

Context

The #394 satisfaction pressure is keyed on nearestLobbyFloorDistance, raw floors from the nearest (sky)lobby. The wait-time-centered reading of the 1994 original is that tenants suffered from elevator WAIT and TRANSFER time; sky lobbies mattered because they were the express-to-local transfer layer, not because altitude itself was a tax. A floor 7 out from a starved, shaft-poor sky lobby should feel worse than a floor 7 out from a well-served one; today they read identically.

Idea

Re-key the drain on effective reach instead of altitude:

• Gate on whether the floor is served by an express-connected (sky) lobby within one transfer and an acceptable wait, computed from elevator/escalator access and transfer count against the shared 24-shaft pool.
• Per-mode divergence rides GameRules as usual: Classic moves toward the wait/transfer model; Modern may keep a labeled graduated distance ramp as a deeper-economy invention.
• Gives the optimizer a real trade surface (shaft budget vs coverage vs rentable-floor yield) instead of a fixed geometric band.

Scope

A new subsystem touching transport pooling, routing, and both rule-sets, with a large determinism surface: spec-first, its own gdd/arch pass, NOT a rider on any other PR. Interacts with elevator-scheduling #305 (wait times) and contiguous-skylobby-transfer #396 (transfer admissibility); sequence after those land or fold into their spec. /gds-code-review; golden re-pins expected in whichever PR ships it.

Begin with the specs or game-design/architecture material for this feature, then review #305 on elevator-scheduling and #396 on contiguous-skylobby-transfer, which this work depends on. Trace the transport pooling, routing, shared 24-shaft pool, and GameRules boundaries before implementation. Done means a spec-first change covering both rule sets with deterministic behavior and updated golden expectations.
