fix: rendering of Markdown inline formatting and bullet lists (#1156)

Markdown inline formatting (**bold**, *italic*, `code`) and bullet lists
using "- " markers were not rendered in the HTML output.

Inline formatting:

- Add `appendMarkdownInlines()` to parse **bold**, *italic*, and `code`
  spans in text nodes, producing `StrongInline`, `EmphInline`, and
  `CodeInline` nodes respectively.

- Call it from `visitText()` so all text nodes are processed.

- Add a markup/b.html.hbs partial to render <strong> tags.

- Add doc/inline.html.hbs to dispatch text, strong, emph, and code
  inline kinds to their partials without emitting extraneous blank
  lines.

List detection and conversion:

- Add list marker detection functions that recognize "- " at the start
  of text, after newlines, after ":" or "." punctuation, and at trailing
  positions within already-started lists.

- Add `convertParagraphWithLists()` to split a paragraph containing list
  markers into a prefix paragraph and a `ListBlock`.

- Apply list detection in `visitParagraph()`, `@par` blocks, and `@li`
  blocks so that Markdown lists are converted in all contexts.
