Align Recipe pyproject.toml

Use this skill to bring a Python recipe's pyproject.toml (and, when it disagrees, its manifest.yaml description) into conformance with the repo standard enforced by .github/workflows/python-validate-recipe.yml.

Scope: pyproject.toml only. Standalone ruff.toml / .ruff.toml files are also forbidden in recipes but are enforced by the CI workflow (Check 7 in python-validate-recipe.yml) — outside this skill's concern.

Not in scope: adk-major-current. The CI validator also emits a warn-only notice when a core/ recipe resolves to an older google-adk major. This skill deliberately does not implement it, and you should not add it. The mechanical fix — widening <2.0.0 to <3.0.0 and re-locking — produces a recipe importing a major it was never ported to, and that break surfaces at runtime rather than in any check. Crossing an ADK major is a code migration; this skill only rewrites metadata. If you are asked to "fix the ADK notice", port the recipe by hand.
