v1.0.0

First stable release of the V1 surface. Promotes 1.0.0-beta1 to GA
with the additions and fixes listed below. The post editor, site
editor, artisanpack/* block fork, and first-class
artisanpack-ui/cms-framework pairing — all introduced across
1.0.0-alpha.1 and 1.0.0-beta1 — are now considered stable. See the
README and the docs/ directory for the full V1
surface.

Added

• Laravel 13 support. illuminate/support constraint updated to
  ^11.0|^12.0|^13.0 (Laravel 5.3–10 are no longer supported — the
  previous >=5.3 floor was effectively dead code, since orchestra/ testbench already pinned us to Laravel 11+). Laravel 13 requires
  PHP 8.3+, which is enforced transitively through L13's own php
  constraint; the package PHP floor (^8.2) is unchanged for users
  staying on Laravel 11/12.

Fixed

• Paragraph block-gap spacing. Paragraph blocks now correctly
  inherit is-layout-flow block-gap spacing in the rendered output
  (#540).
• artisanpack/post-title editable inline. The post-title block
  now edits the live entity directly instead of getting stuck on its
  initial value (#546).
• FontSizePicker duplicate-key warnings. Font-size presets are
  now deduplicated before being handed to FontSizePicker, silencing
  the React duplicate-key warning that surfaced under certain
  theme.json configurations (#547).
• tsc --noEmit errors in the core-data shim. Resolved the
  TypeScript errors surfaced by tsc --noEmit in the core-data shim
  and its tests (#542).
