Improve Rust call graph receiver resolution

[forhappy]

Summary

• recover exact Rust calls through source-proven Arc, Rc, and Box field chains
• propagate typed call-result receivers into chained member-call resolution
• recover calls from bounded local macro_rules! inputs only when an expr or stmt fragment is proven to be evaluated
• preserve fail-closed behavior for unsupported macro shapes, ambiguous receiver owners, custom dereference implementations, and non-evaluating inputs
• advance the Rust evidence producer version so cached Rust evidence rebuilds automatically

Compatibility

• graph and evidence schema majors are unchanged
• Rust extraction caches from producer version 1 rebuild on first use
• no manual graph migration is required

Verification

• cargo fmt --all -- --check
• cargo clippy --workspace --lib --bins --locked -- -D warnings
• cargo test --workspace --lib --bins --locked
• Rust universal evidence integration suites
• universal evidence promotion validator and tests
• sh scripts/check_product_boundary.sh
• ./scripts/qualify_code_graph_v1.sh --fixtures-only
• release builds and fresh extraction of five pinned real repositories
• ten source-grounded CLI query, path, and explanation tasks
• git diff --check
