Document-model foundation for section-style plugins (ADR 0008 kind
section_style): a `section` block node carrying `pluginId` + `styleId`,
rendered as `<div class="dt-section dt-style-<pluginId>-<styleId>">` so a
plugin's sanitized, scoped CSS applies and — when the plugin is gone —
the class matches nothing and the content stays intact with neutral
styling. Round-trips to a Pandoc-style fenced div
(`::: {data-section-style="<pluginId>/<styleId>"}`), with a markdown-it
block rule that supports nesting.
This is the schema/markdown/HTML half of #75; the editor UI (wrap/style
picker/unwrap), the `section-styles-basic` reference plugin, per-pond CSS
injection, and PDF/office export styling follow in part 2. The node is
additive and backward-compatible (existing documents have none).

Introduce Obsidian-style `[[page links]]` (ADR 0004).
- shared: reserved `wikilink` inline atom in the editor schema (attrs
`targetSlug`, optional `displayText`); markdown mapping `[[slug]]` /
`[[slug|text]]` via a markdown-it inline rule + serializer node; plain-text
and HTML derivation include the shown text. Round-trip + parse unit tests.
- web:
- `Wikilink` node extension with a React NodeView: shows the explicit
display text or the target's current title (so a rename updates the link),
renders a missing target as a dashed phantom with a tooltip, navigates on
click in read mode.
- `[[` autocomplete popup (`WikilinkAutocomplete`), dependency-free: filters
the pond's pages as you type with a create-new-page hint for misses,
Enter/click inserts the node and removes the typed `[[query`; ↑/↓/Enter/Esc
intercepted in the capture phase so ProseMirror does not act on them.
- `WikilinkContext` provides the pond's pages (slug→title) for live
resolution and the autocomplete, populated by the page editor.
- i18n `editor.wikilink.*` (de + en); wikilink + phantom + popup styles.
- e2e `wikilink.spec.ts` (new CI pack): type `[[`, autocomplete filters and
inserts a working link that resolves the target title and persists across a
reload. Phantom → live resolution on page creation is verified in #47.

ProseMirror schema (headings 1-4, lists incl. task lists, blockquote,
code block, tables via prosemirror-tables, images, hard breaks; bold/
italic/code/strikethrough/link marks) plus docToMarkdown, markdownToDoc,
docToPlainText, docToHtml, and extractOutline built on it. Markdown
parsing extends markdown-it's default preset with a token-stream
transform for GFM task lists and table-cell paragraph wrapping.
docToHtml hand-rolls escaping and link-protocol allowlisting with zero
DOM dependencies, so it runs in the API/collab server as well as the
browser.
Node names `wikilink` and `plugin_block` are reserved for later stories.
Closes#24
