v0.21.2

🐞 Fixes

• groove-admin-claude-statusline — faster and more robust rendering. The stdin payload and usage JSON are each parsed in a single jq pass (~2× faster warm render); the 5h/7d usage limits now refresh in the background with an atomic cache write, so a stale cache never blocks the render on the up-to-10s API call; the git counter uses git diff HEAD to include staged + unstaged changes (matching the documented "staged diff" behaviour); and the @reset time now shows on Linux (the macOS date branch previously masked the GNU fallback via the pipeline exit status). Also fixes a field-alignment bug where an absent effort value shifted the repo column.
