initial commit: @arbiter/core authorization engine with js-rigor hardening

Zanzibar-style authorization graph engine (direct/chain/TTU/defeasible/
binary modes, condensed snapshots, value relations) with 39 rigor test
campaigns. Includes fixes for snapshot binary writer/reader format
mismatch (snapshot-of-snapshot corruption), possibility write-boundary
validation, empty-graph snapshot serialization, relation lookup cache
direction collision, config-redefinition cache invalidation, binary
threshold semantics, defeasible compiled routing, and comparator
reason whitelisting.
