feat(workflows): session-harvest monthly promotion-mining pass

session-harvest runs a monthly pass over recent session summaries across every AI project and proposes promotion candidates in four lanes: patterns catalog, KB facts, rule refinements, workflow learnings. Capture already happens continuously. This adds the batched review cadence that turns it into curated promotion.

The window filter reads each session filename's date prefix instead of mtime. Clones and syncs reset mtime, which let 2025 sessions pass a recency filter. The run also aggregates the KB receipt lines from session summaries, so it doubles as the 30-day KB metrics readout.
