Skills become installable anywhere, and Project Drawdown gets structured

The skill playbooks moved out of .claude/ into a top-level skills/ directory in the flat layout npx skills expects, so any agent can install them — npx skills add datasets/datapressr — not just Claude Code, which keeps working through symlinks. The three last-mile commands (init, validate, push) became SKILL.md playbooks alongside capture, archive, and structure, so there is now one consistent format for all six.

Project Drawdown's 2020 Table of Solutions was run through structure: a reproducible build.ts, two tidy typed CSVs (82 solutions × 2 scenarios; the solution-to-sector links), validation clean. drawdown.org's own site terms are all-rights-reserved, but the dataset is just the numbers — measured and modelled emissions-impact estimates, which are facts and not per se copyrightable — restructured into tidy tables, not the prose or figures. We release the compilation as PDDL-1.0 and attribute Project Drawdown as the source. It still needs relocating into the datasets/climate-and-environment catalog repo before it goes live.
