v0.57.0

Retire per-repo .claude/commands scaffolding (plugin migration, Phase 4)

The dotmd Claude Code plugin's workflow skill is now the single source of truth for agent guidance, so dotmd no longer generates per-repo slash-command files.

Upgrade behavior: on the next dotmd hud (SessionStart), dotmd removes retired generated command files — only banner-stamped (<!-- dotmd-generated -->) plans.md / docs.md / baton.md. Hand-authored command files are never touched. If you'd committed the generated files, you'll see deletions to commit (expected). Run claude plugin update dotmd@dotmd to pick up the /baton command, now shipped by the plugin alongside /plans, /docs, /prompts.

• dotmd init recommends installing the plugin instead of scaffolding
• dotmd hud / dotmd doctor sweep stale generated files
• /baton ported into the plugin (plugins/dotmd/commands/baton.md)
