Adds Seth's homelab convention files on top of upstream glabels-qt master: CLAUDE.md (project instructions), IDEA.md (brief), DECISIONS.md (decision log, empty), and the kickoff handoff under .claude/handoffs/. Appends a clearly-marked sethLabels section to .gitignore for .backup/, the GITEA_API.md symlink, .env files, and handoff drafts. This is the only non-upstream commit on main. All preceding history is authored by the glabels.org team (Jaye Evins et al.) and untouched. Future upstream merges should fast-forward or rebase cleanly since the scaffold lives in distinct files at repo root. No source-code changes. License unchanged (GPL-3.0).
