chore(.machine_readable): convert 6a2 checkpoint files from Scheme to A2ML
Convert all .machine_readable/6a2/ files from Guile Scheme format to A2ML (a2ml) format. Preserves all data (project name, version, milestones, blockers, actions) in the A2ML TOML-like structure. Also fills in unfilled template placeholders ({{CURRENT_YEAR}}, {{AUTHOR}}, etc.) with concrete values. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
