Forward declaration — defined in rust_cargo.h. We keep it forward * here to avoid pulling rust_cargo.h into every consumer that only * needs the LSP

Borrow the (thread-local) Rust Cargo manifest the cross-file LSP pass set for * cross-crate (#56) routing. The Tier-2 prebuilt Rust resolve reads it

The opaque CBMHashTable struct holds the Verstable instance + a * count cache (Verstable's _size traversal is O(buckets) so we keep * our own atomic

Phase 4: Parallel call/usage/semantic resolution. * Each worker resolves calls, usages, throws, rw, inherits, decorates, * and implements edges into
