Replace the custom regex-based ViewPlugin with the official
@codemirror/lang-yaml package. yamlFrontmatter({ content: mdLS })
wraps the Markdown language with a mixed parser: the leading ---/---
block is handed to the full Lezer YAML parser (proper key/value/scalar/
anchor/alias highlighting), while the document body continues to use
the Markdown parser. The manual Frontmatter extension import is also
removed since yamlFrontmatter handles frontmatter recognition itself.

Typst: heading tokenizer now colors the entire heading line (not just the
'=' prefix), and bold/italic markers (*/_) map to strong/emphasis tags
rather than the generic operator tag. A typstHighlightStyle applies
bold/italic formatting even when the active theme lacks .tok-heading.
Quarto: enable @lezer/markdown's Frontmatter extension so the YAML header
is no longer mis-parsed as Setext headings. A new ViewPlugin decorates
frontmatter lines with type-appropriate CSS classes: keys (tok-typeName),
string/bool/number values, comments, and the --- delimiter markers.

- Add a Typst language (stream highlighting + completions) for .typ, and
Quarto completions (code chunks, callouts, cross-refs) for .qmd/markdown.
- Project dashboard: new Format column (Quarto/Typst/LaTeX) from the cheap
project compiler field, surfaced through the projects list API.
- Compiler dropdown: grey out engines that don't match the root file's
extension (.qmd->Quarto, .typ->Typst, .tex->LaTeX engines).
- Replace the Overleaf fill loader with an animated Verso logo: the four
quadrant circles drift on their own orbits while colour warms up with load
progress; reused on the token-access screen too.

Two fixes to the Markdown/Quarto file outline:
1. The last frontmatter line (e.g. `format: typst`) appeared as a
heading. The Lezer Markdown grammar has no frontmatter support, so it
reads the closing `---` of the YAML block as a Setext underline and
promotes the line above it to a heading. Detect the leading
`---`...`---`/`...` block and skip any heading inside it.
2. Pandoc/Quarto attribute blocks were shown in titles, e.g.
`## Slide {.smaller auto-animate="true"}`. Strip a trailing `{...}`
from the extracted title.

The outline entries showed up at the right lines and jumped correctly,
but their titles were blank. The text-extraction walked the heading
node's children and collected non-HeaderMark child text — but in the
Lezer Markdown grammar a heading has NO child node for its text; the
only children are the HeaderMark nodes. The title text lives in the
gaps between marks, so the walk collected nothing.
Slice the whole heading's source instead and strip the markers:
leading/trailing '#'s for ATX headings and the '==='/'---' underline
for Setext headings.

outline.ts: export NestingLevel so it can be used outside the file.
markdown/document-outline.ts: new enterMarkdownNode function that walks
the Lezer Markdown syntax tree and extracts ATXHeading1-6 and
SetextHeading1-2 nodes, mapping them to the same NestingLevel enum
used by the LaTeX outline (Section→SubSection→SubSubSection…).
Wrapped in makeProjectionStateField for incremental updates.
markdown/index.ts: register markdownDocumentOutline as a CodeMirror
extension in the Markdown LanguageSupport so the StateField is active
whenever a .qmd file is open.
codemirror-outline.tsx: fall back to markdownDocumentOutline when the
LaTeX documentOutline StateField is not present in the editor state
(i.e. when the active language is Markdown, not LaTeX).
