fix(opy-compiler): lower declared macros before WIR

[e54-bot]

Summary

• expand declared OPY macros before canonical Workshop WIR lowering
• preserve frontend HIR macro calls for semantic tooling
• retain structured diagnostics for recursive and invalid macro expansion
• add the include plus macro regression through the public compile path

Verification

• cargo fmt --all -- --check
• cargo clippy --workspace --all-targets --all-features -- -D warnings
• cargo test --workspace --all-targets --all-features
• python3 -m unittest discover -s compatibility/tests
• git diff --check

Refs #85

Reviewed against #85 scope and acceptance criteria. The owner-side macro expansion is correctly resolved before canonical WIR lowering, structured diagnostics are preserved for the demonstrated failure modes, and the public compile-path regression covers the reported include + macro case. CI is green. PR body was adjusted to Refs #85 so the issue remains open until the released owner contract is consumed and verified downstream by wright#228.
