Run the weekly Sunday blessing ritual on a builder's work — witness what shipped, ratify what is whole, name what to ignore for seven days, and surface the one path forward. Use when the user says "run the weekly blessing", "do my Sunday review", "bless this week", or invokes /sunday or /bless. Writes weekly/YYYY-W##.md and appends to the blessing ledger. Invoked, never auto-fired.
