Refactor plan render pipeline to use `@refrakt-md/html`

The main refactor: replace the bespoke HTML shell template in @refrakt-md/plan with calls to renderFullPage() from @refrakt-md/html. This removes the hand-rolled document structure, inline styles, and direct HTML string concatenation.

Add work items WORK-037 through WORK-049 for plan site specs

Acceptance Criteria

render-pipeline.ts calls renderFullPage() from @refrakt-md/html instead of building HTML strings
The bespoke HTML shell template is removed
getLuminaBaseCss() is removed — @refrakt-md/lumina is no longer a dependency
escapeHtml utility is removed (handled by the HTML adapter)
Built-in theme CSS is served at /__plan-theme.css (serve) or written to theme.css (build)
SSE hot reload script is injected via headExtra option
planLayout from WORK-037 is used for structural placement
Nav region from WORK-038 is passed as regions.nav
plan serve produces identical visual output as before
plan build produces identical static output as before
--theme flag still works for default, minimal, and custom paths
--base-url flag still works correctly
All existing plan serve/build tests pass

Approach

Add @refrakt-md/html as a dependency of @refrakt-md/plan
Remove @refrakt-md/lumina dependency
Assemble a minimal HtmlTheme with planLayout
Replace the HTML shell with renderFullPage() calls
Move theme CSS from inline <style> to external stylesheet references
Update serve command to serve CSS and behaviors at dedicated routes
Update build command to write CSS and behaviors as separate files
