release: v0.14.0

Fourteen commits since v0.13.0. See CHANGELOG.md for the full list.

Two additions: `npm run doctor`, which runs the config doctor from a terminal — including inside the shipped image — and exits with the worst finding, so it can gate a deployment script; and a Playwright spec that loads all fourteen admin routes against a production build.

One change, invisible on screen: the admin panel got a form-field layer (#533).

Five fixes: grid.gap on both axes (#513), the dashboard status badge (#539), the journal editor's unsaved-changes guard (#538), essay paragraph markup (#537), and aria-pressed on the panel's switches and pickers.
