fix(libsy): restore judge classification test

[nachiketb-nvidia]

What

Restore the LlmJudge test helper to pass the Classification enum directly to selected.

Why

PR #204 changed the helper to access tuple field .0, but Classification is an enum. This prevents cargo clippy --workspace --all-targets -- -D warnings from compiling on main and makes every subsequent CI run fail.

Validation

• cargo fmt --all --check
• cargo clippy --workspace --all-targets -- -D warnings
• cargo test -p switchyard-libsy
• uv run ruff check .
• uv run maturin develop
• uv run pytest tests/ (1729 passed, 35 skipped)

Summary by CodeRabbit

• Bug Fixes
  • Improved policy selection by preserving the complete classifier result when evaluating served content.
  • Ensured judge-based scoring uses the full classification outcome for more accurate decisions.

Poem

I’m a rabbit hopping through the code,
Carrying the verdict’s full payload.
No tuple nibble left behind,
Selection now sees the whole design.
Hop, hop—cleaner judgment today!
