feat(06-04): /api/route engine-A arm + http-source backend #2 — Bearer-gated, honest-null, RP re-pinned (GREEN)

- bot/src/routing/worker-router.ts: module-scope per-env graph memo (1 R2 GET per
  cold isolate, shared with the 06-07 cron arm via loadGraph), snap+A*+deriveSteps,
  claim-gated 401 / 4096-cap 413 / V5 bbox 400, 200-null on every miss class,
  ONE best route (no alternatives), category-only logs
- webhook.ts: /api/route arm delegating to handleRoute (405 non-POST)
- config.ts: ROAD_GRAPH: R2Bucket — first R2 binding (never a KV namespace, GE5)
- wrangler.jsonc: r2_buckets ROAD_GRAPH -> araharah-graphs with the fork law comment
- routing/src/http-source.ts: createHttpRoutingSource — slug-guard-first, fail-honest
  (throw/non-200/malformed/null-body -> null), defensive RouteResult validation;
  exported from index.ts; ladder note: backend #2 LIVE
- A7 re-pinned (06-01 named 06-04 as the owner of createHttpRoutingSource)
- test-side fix during GREEN: the R2 fake hands decodeGraph an exact ArrayBuffer
  (Node Buffers are views; encodeGraph output is already an ArrayBuffer)
- bot 103 passed / routing 65 passed; both typechecks clean

feat(06-01): typed-array A* + turn classifier + step derivation + public exports (GREEN)

- routeAstar: allocation-free hot loop — binary heap of node indices over
  preallocated typed arrays (grown by doubling), typed-array g/closed/
  came-from, on-demand cached haversine/maxSpeed heuristic (admissible +
  consistent); oneway-reverse edges never relaxed; unreachable -> null
- A1 proves A* == brute-force Dijkstra on ALL 625 mini-graph pairs
- classifyTurn: the one turn authority (compass convention — negative
  delta = left; plan's (0,40)->slight-left case contradicted its own
  (0,-90)/(0,90) pins, documented deviation); TURN_* constants exported
  for plan 07's cron projection
- deriveSteps: splits at non-straight bearings or name changes; steps
  carry kind/name/distanceM + polyline6; depart-first, arrive-last
- index.ts: engine-A named exports + ladder note updated — backend #2 is
  now 'engine-a' (D-01 supersedes the wasm-router note; Valhalla port
  infeasible + geojson-path-finder rejected, engine B = post-v1
  evolution, D-02); createHttpRoutingSource deliberately absent (plan 04)

feat(05-01): geo math + fixture RoutingSource backend + public API

- geo.ts: haversineM + deriveCumulativeDistanceM (D-07 snapped-progress field)
- fixture-source.ts: backend #1 — ORIGIN_TOLERANCE_M=200 matching law,
  honest-null pending semantics (D-03), defensive pair skip at index build,
  lazy memoized index (LAW 1), static JSON import (LAW 2), zero
  logging/storage/network (LAW 3, D-12)
- index.ts: named-export public surface, subpath-with-extension import law
- loader proven in three environments (bare Node 24, esbuild, Vite-family)
