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.
