Map resolved enums into scalar ABI

[jscott3201]

Summary

• add frozen caller-supplied mappings from local enum members to canonical source enum classes and literals
• project mapped enum parameters and active connectors as class-qualified, one-based ordinal values
• validate mapping coverage, uniqueness, source membership, and required mappings before allocating output rows
• retain the existing fail-closed behavior when a required enum mapping is absent

The successful regression is grounded on Buildings.Controls.OBC.ASHRAE.G36.Types.HeatingCoil at both pinned Buildings revisions (None, WaterBased, Electric) and the enum representation at the exact Engine pin. Caller mappings remain reviewed internal input; they do not perform source verification or establish a public compatibility/provenance contract.

Public schemas, persisted mappings, scalar names/IRIs, source maps, graph/CXF generation, production routines, registries, 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 (36 tests)
• python3 -m unittest discover -s tools/lint/tests -v (141 tests, pinned schema environment)
• python3 tools/lint/routine_schemas.py
• python3 tools/lint/routine_semantics.py
• python3 tools/lint/routines.py
• G36 source inventory check against both exact pinned source checkouts (431/693 files)
• 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
• python3 tools/book/generate.py && mdbook build book with no tracked generated changes
• git diff --check

Cycle 1 consolidated review — PASS at 55a6e088c356e878a9e9ae204b78bbc7d8f507f1.

Both independent reviewers found no blocker, major, or deferred minor finding. Mapping validation is atomic and deterministic; default fail-closed behavior, inactive connector omission, primitive/alias behavior, and the internal-only boundary are preserved.

Exact-head build and verify checks are green; deploy is skipped as configured.
