Harvest — Cross-Rig Knowledge Consolidation

Usage: /harvest is for manual sweeps and CI runs. (The old /dream start nightly loop that wrapped harvest is retired — out-of-session compounding moved to Gas City; there is no live Dream process or .agents/overnight/run.lock to wait on.)

Sweep all .agents/ directories across the workspace, extract learnings, patterns, and research, deduplicate cross-rig, and promote high-value items to the global knowledge hub (~/.agents/learnings/).

Naming gotcha. $harvest promotes into ~/.agents/learnings/, not ~/.agents/. Users often say "harvest all to ~/.agents" and mean the promotion hub. If you really want every raw artifact (not just the promotion set) mirrored verbatim, you want rsync, not $harvest.
