Fix the validate_posts workflow failure caused by malformed metadata in _posts/2026-05-01-thick-skin-sass.md.
The post front matter currently has a date value that does not match the parser format expected by scripts/validate_posts.py:
date: 2026-04-23 10:10That value is missing seconds and the UTC offset. The file is also future-dated, so the validator will require a matching companion snippet in _snippets/.
_snippets/2026-05-01-thick-skin-sass.md file with aligned metadata._posts/2026-05-01-thick-skin-sass.md_snippets/2026-05-01-thick-skin-sass.mddocs/superpowers/plans/2026-04-23-validate-posts-thick-skin-date.mdpython3 scripts/validate_posts.py --today 2026-04-23 exits cleanly.
