test(08-02): bot-suite encodeGraph call sites carry landmark blocks (full battery green)

webhook corridor/sparse builders + guidance-cron unnamed way compute
tiny tables through the ONE preprocessing core (@araharah/routing
farthestPointAnchors + landmarkTables) and pass the landmarks block
into the same single encodeGraph call — call-site updates, not a
second encode function. Graphs with no degree>=2 candidate (sparse,
2-node) pin their anchor explicitly; tables still come from the
integer-Dijkstra core.

FULL BATTERY at this commit: routing:test 74/74, bot 126/126, both
typechecks clean; the regenerated fixture is deterministic (byte-
identical re-run); mini-graph-arg1.bin is byte-stable vs its committed
08-01 bytes.
