fix: gracefully handle outdated skills-lock.json in copilot setup workflow

Copilot · nathanjmcdougall · web-flow · commit e1dbc85be214 · 2026-04-03T20:38:27.000Z
Instead of failing the step when skills-lock.json is out of date: - Emit a warning annotation - Delete .agents/skills directory (stale external skills) - Revert all working tree changes - Continue without failing Also add GIT_CONFIG_* env vars for reproducible hash computation. Resolves #1779 Agent-Logs-Url: https://github.com/usethis-python/usethis-python/sessions/4eae6f6e-af38-472f-b7b4-671eda64b9b3 Co-authored-by: nathanjmcdougall <18602289+nathanjmcdougall@users.noreply.github.com>
