Add internal scalar ABI projection

[jscott3201]

Summary

• add a pure internal projection from ResolvedSpecialization to ordered scalar parameter and active-connector rows
• preserve structured authored coordinates, primitive and alias metadata, parameter values/sources, and connector directions
• omit inactive connectors and reject enum parameters or active enum connectors with deterministic typed diagnostics

The projection deliberately assigns no scalar string names or enum codes. Public deployment schemas, IRIs, source maps, graph/CXF contracts, production classes, registries, provenance, and Engine or Studio changes remain deferred.

Validation

• python3 -m unittest tools.lint.tests.test_routine_resolution tools.lint.tests.test_routine_scalar_abi -v (28 tests)
• python3 -m unittest discover -s tools/lint/tests -v (133 tests, pinned schema environment)
• python3 tools/lint/routine_schemas.py
• python3 tools/lint/routine_semantics.py
• python3 tools/lint/routines.py
• python3 tools/lint/g36_source.py --check ... against both exact pinned source checkouts
• cargo test --manifest-path tools/verify/Cargo.toml (11 tests)
• cargo run --quiet --manifest-path tools/verify/Cargo.toml -- --routines
• cargo run --quiet --manifest-path tools/verify/Cargo.toml -- --all
• python3 -m unittest discover -s tools/dataset_harness/tests -v (32 tests)
• exact tiny LBL FPU replay and assertions from verify.yml
• git diff --check

Cycle 1 consolidated review — PASS at bbc8c095049c773ba5a38d7706d90ecfd33f2ff2.

Both independent reviewers found no blocker or major issue. Exact-head build and verify checks are green; deploy is skipped as configured.

Deferred non-blocking observation (OBS-79-1): the projection's runtime casts rely on the resolver's validated type invariant. No concrete failure was identified, and no code change is requested.
