0.2.0

Two months of work on the shared editor engine, most of it making the Markdown
right rather than adding anything new.

CJK

• Full-width and non-breaking spaces no longer break structure. The engine
  matched structural whitespace with \s, and in JavaScript \s includes
  U+3000 (the ideographic space) and U+00A0 — so an ideographic space after a
  # or a -, which is ordinary in Chinese and Japanese typesetting, was read
  as a heading or a list item when it is neither. Structural whitespace is now
  a space or a tab, and nothing else.

Emphasis, by the specification's own algorithm

• Emphasis nests. **bold with _italic_ inside** is now resolved with
  CommonMark's delimiter-run stack instead of a regular expression, including
  the rule-of-three and the intraword rule that keeps snake_case_names
  unstyled.
• __bold__ and _italic_ are supported, with that same intraword rule.
• Code spans and autolinks bind tighter than emphasis, so a * inside
  backticks stays a literal asterisk.
• Backslash escapes no longer reach inside a code span — `\d` keeps
  its backslash, as it must.

More of standard Markdown

• Setext headings (=== and --- underlines).
• A fenced code block is no longer parsed as Markdown, and neither is
  frontmatter.
• Syntax highlighting inside a fence, and an honest decline when the language
  is one it cannot highlight.
• CommonMark conformance is up from 57% to 63% of the official suite.

Rendered mode

• Lists render as lists, task checkboxes are pressable, and the icons match
  Lucide, so they sit with the rest of Obsidian.
