Christoph LeiterandClaude Opus 5 3d69b0f458 fix(app): render markdown verbatim instead of substituting characters (#3253)
markdown-it's typographer option rewrites characters after parsing, so
a literal (c) came out as ©. Agents label steps and options (a), (b),
(c) all the time, and an ordinary list rendering as (a), (b), © stops
your eye every time.

The same option turns ... into an ellipsis, --- into an em dash, and
straight quotes into curly ones. Agent output is text people paste
back into a shell or a file, so a curly quote in --name="my repo"
looks correct on screen and fails when pasted. The markdown file
preview had the same problem, showing characters that are not in the
file on disk.

Every in-app markdown surface now goes through one factory in
utils/markdown-parser.ts, which leaves typographer off: agent chat,
plan cards, pull request comment bodies and the file preview. The plan
card was rendering through its library's built-in parser because it
never passed a markdownit prop, and that default has typographer on.

Link behaviour is unchanged. The assistant parser keeps its file://
permission and no other surface gains it, and linkify stays on for
chat and the default renderer and off for plan cards, matching what
each did before.
