Gate python cli-output tests on deptry as well as ruff

[LiinaSuoniemi]

What

Gate the two Python cases in src/cli-output.test.ts on deptry as well as ruff.

Why

The Python preset runs both ruff and deptry, but these cases were gated on ruff only (skipIf(!RUFF)). With ruff present and deptry missing, the "python clean run" case fails: deptry's spawn failure forces exit 1, while the case expects exit 0 on a clean project. python-acceptance.test.ts already gates on both tools for this reason; this brings cli-output.test.ts in line.

Changes

• src/cli-output.test.ts: RUFF → PY_TOOLS (ruff and deptry), and the two it.skipIf(!RUFF) → it.skipIf(!PY_TOOLS).

Test-only, no production code touched.

Testing

On a clean main:

• deptry hidden, before the change: "python clean run" fails (expected 0, got 1). Bug reproduced.
• deptry present, after the change: both Python cases run and pass.
• deptry hidden, after the change: both Python cases skip, nothing fails.
• full suite green with ruff and deptry installed (501 passed).

[devill]

Correct root-caused gating fix: a missing deptry hits recordSpawnFailure -> sink.failures -> exit 1, so the clean-run case must require both tools to assert exit 0. Brings cli-output.test.ts in line with python-acceptance.test.ts. Test-only.
