Move integration architecture rework (PR #2682): new cross-package move-linker, closure-capture edges via function_usage, hardened mcp-client (typed timeout/transport errors, serialized package queries), binary-content cache fingerprinting, generic Type node table, external-node incremental rebuild with partial-snapshot preservation, entry-point process roots with tier interleaving. INCREMENTAL_SCHEMA_VERSION 15: existing aptos indexes do one full re-analyze on first use. Install: npm i -g gitnexus@aptos
