Ship a default recipe for the page-box drag move

Outcome

A completed page-box drag in Quick can run to a published, revalidated artifact on a default installation. Today the drag proposes a move that cannot execute, because no shipped recipe offers translate-page-box.

Parent and boundary

Parent: #4 (L03 - Quick Workspace). Follow-up to #104 (actionMoveSelection, ADR-012). Plan, approval and execute remain the Fix workspace's; the command catalog remains the only route in, and this issue adds no second mutation path.

Grounding

• ADR-012 implementation notes: "With no recipe offering translate-page-box, the command fails with move/rejected and the host announces that a recipe is needed; there is no built-in recipe, so the drag proposes a move but cannot execute one until the operator imports one."
• docs/QUICK_CANVAS_EDITOR_GAPS.md: "The move needs a recipe that offers translate-page-box; none ships built in."
• The recipes directory is empty in every test and smoke environment (docs/WORKSPACE_SURFACES_586.md), so no existing sample can satisfy the drag.

Acceptance

• One recorded decision for where the recipe ships (bundled sample recipe, profile entry, or first-run onboarding step), including where it lives for an installed package and how it is versioned or updated.
• One end-to-end default-install run: drag a page box, the proposal binds to the recipe, plan, approval, execute, exact published-byte revalidation, with the artifact identity recorded.
• A user-imported recipe remains supported and is not silently shadowed by the shipped one; precedence is recorded.
• Failure case: with the recipe absent, stale, or offering a removed operation, the move still fails closed with the typed move/rejected reason and a message naming what is missing.

Required proof

A quick-lane or acceptance test that drives the default journey over a representative fixture, plus the decision record. Record the exact source SHA, test command or hosted run, fixture identity, and any skipped lane. Run the repository's mapped proof and check-change gate for a PR.

Handoff

Record changed files, observed result, remaining risk, and a 1-3 sentence anti-slop review. Completion means acceptance evidence, not merely a merged implementation.
