feat(06-04): R2 upload + A*-CPU measurement gate + the A1 ladder executed to its decision point

- upload-road-graph.mjs: wrangler-shelled maintainer tool (pre-flight 1-80MB,
  round-trip verify hint); bucket araharah-graphs NOT created — R2 is not yet
  enabled on the account (wrangler code 10042) — dashboard one-time activation
  is the phase's user_setup item
- measure-route-cpu.mjs: 25-pair gate (corpus + seeded quadrant spread),
  hrtime around routeAstar, warm-up excluded, unreachable probes reported
  SEPARATELY from the routed p95, exits 1 over the 8ms budget
- Rule 1 (measured): the class set lacked *_link ramps — the graph FRAGMENTED
  (7.7% of nodes in severed motorway islands; corpus pairs 'unreachable').
  5 link classes added -> 311325 nodes / 677068 edges / 14.7 MB, all landmarks
  in one component; enforced floor corrected 1KB -> 1MB (D-01)
- ladder (a) drop tertiary+residential: p95 17.8ms but 12/25 pairs unreachable
  — REJECTED on correctness (D-03), reverted, ladder history recorded
- ladder (b) bidirectional A* (BH, Ikeda potentials, reverse-CSR WeakMap):
  provably optimal (A1 625-pair sweep green), alternation balanced by heap
  size (raw-top comparison starves the backward side 19501:3), reduction
  signs in the standard feasible form. Measured: p95 ~38-93ms — NO GATE PASS.
  The potential split halves each side's steering, cancelling the halved radius
- GATE FAIL is the honest verdict: ladder (c) — Workers Paid vs layout-v2 ALT
  (still $0) vs free-plan-with-degradation — requires maintainer sign-off;
  docs/ROAD-GRAPH.md carries the decision table and the fork contract

feat(06-04): road-graph build tool — Overpass extract → pinned CSR binary with the D-01 stats gate

- maintainer-time repo tool (nothing in bot/web/routing src imports it): drivable-class
  Overpass extract (Pitfall 1 filter), nodes deduped by rounded coord, oneway/-1/roundabout
  flag law, maxspeed-tag overrides over class defaults, name-pool interning
- bbox derived mechanically from the committed corpus (gazetteer entries + golden pairs
  ± 0.05 deg, printed) — Open Q 4's pinning
- collect-then-write + ENFORCED size gate (>1 MB, <=80 MB, exit 1 outside) + advisory
  30-80 MB band warning; --check mode decodes and re-prints the gate, zero network
- routing/data/.gitignore: *.bin is an ODbL-derived build artifact — forks build their own
- real KL graph built: 277514 nodes / 598396 edges / 21447 names / 13.1 MB (gate PASS,
  band warning printed for review)
