v0.6.0 — Lean artifacts: a fixed address on every report

Added

Every review, QA, spec, plan and release report now opens with a short Handoff block right at the top — status, a one-line verdict, what (if anything) is still open, which section has the final ruling, and what wins if the block and the rest of the report ever disagree. You can tell whether a report is done and what's left without reading the whole thing.

Changed

The team members and ceremonies that act on a previous report — the Reviewer doing a re-review, /increment closing out findings, /go-live checking its two release gates, /next-steps scanning for open items across features — now read that new block first, and only read further when they specifically need to (for example, verifying a fix was actually made, or working out a genuine disagreement between the block and the report). Reports written before this change keep working exactly as they did before; nothing about reading them changes.

Fixed

Nothing — this release adds a new capability rather than fixing a defect. No token or byte saving is claimed anywhere: the new block adds lines, it does not shrink anything.
