Subject: [PATCH 1/2] fix(recipes): validate-bundle/validate-single-bundle
 honor AMPLIFIER_PYTHON (v2.1.1 / v2.3.1)

Both recipes used bare python3 in their heredocs, which lacks
amplifier_foundation, so validate-single-bundle's body-instruction check
always skipped with 'amplifier_foundation not importable'. Same fix
validate-agents.yaml received in v1.3.1. Live-verified: the check now runs
and correctly flagged PROSE_BELOW_FRONTMATTER on amplifier-bundle-recipes'
bundle.md.
