feat(routines): add typed Rust source-claim projection

[jscott3201]

Summary

• add typed in-memory G36 inventory, pin, class-claim, and member-binding contracts to the Rust routine compiler
• validate the complete named-scalar-to-source join without filesystem, JSON, declaration, persistence, or runtime coupling
• project detached parameter and connector source-claim rows with forward and derived reverse lookups

Validation

• cargo fmt --manifest-path tools/routine-compiler/Cargo.toml -- --check
• cargo test --locked --manifest-path tools/routine-compiler/Cargo.toml
• cargo clippy --locked --manifest-path tools/routine-compiler/Cargo.toml --all-targets --all-features -- -D warnings
• 189 routine/lint unit tests plus production schema, semantic, catalog, point, registry, and SVG lints
• G36 inventory check: 431 release files and 693 development files
• G36 release declaration conformance
• tools/verify tests, --routines, and --all
• 32 dataset harness tests

Scope boundary

Inventory membership proves only the exact pinned snapshot path and Git blob. Modelica class and member identities remain caller claims; this PR does not parse declarations or add JSON/I/O, persisted source maps, bound-scalar joins, or runtime artifacts.

Reviewed dcc99033b5fa0a6c0e10e6ab71146ad8891a8f74...ae9f55ad5ac75e868f8750828219ca38390eea1c with the holistic and dataflow lenses. No blocker or major findings were confirmed. The typed inventory validation, role-isolated path/blob membership, owner/class/member joins, deterministic atomic diagnostics, detached output, and lookup behavior preserve the intended scope and invariants.

Exact-head build and verify checks are green. Local focused and full gates also passed.

Deferred nonblocking observation: unknown Rust lookups use Option while the existing Python helper raises KeyError; this is an idiomatic API-shape difference, not a correctness defect, and requires no change in this PR.
