Overhaul pdoc template: full dark theme, fixed version bar, hljs palette

- frame.html.jinja2:
  - Load IBM Plex Mono via <link> in {% block head %} (not @import in CSS)
  - Version bar: position:fixed full-width header instead of cramped sidebar
  - Full dark theme overriding every pdoc selector (.attr, .def, .name,
    .docstring, .signature, .param, .label, .admonition, table, blockquote)
  - highlight.js tokens remapped to terminal palette (orange keywords,
    green strings, cyan titles, dim comments)
  - Sidebar top adjusted to clear the fixed bar; scrollbar styled
  - Scanline texture overlay (matches root version index)
  - Status badge auto-classifies: DEV / ALPHA / BETA / STABLE from URL
  - Home link href set by JS to work at any nesting depth
  - Source blocks: custom [ source ] summary replacing browser default arrow
- index.html: update badge to BETA 0.2.0, footer link to pdoc.dev
