- Allow suvi to be served below a sub path by a reverse proxy.
- New options `--url-prefix`, `--url-scheme` and `--trusted-proxy`.
- Build all static file links relative to the sub path.
- Scope the session cookie to the sub path and mark it `Secure` for `https`.
- Render the task, process and task log lists on the server again instead of
  leaving the page empty until htmx has fetched them.
- Remove stray `</main>` and `</body>` tags from the task log list partial.
- Let browsers cache static files and stamp their links with the file date,
  so a page change no longer reloads the stylesheets.
- Compress text responses, which shrinks a full log page from 270 KB to 5 KB.
  Uncompressed, such a page delayed its own stylesheets and showed up unstyled.
- New option `--threads`, raising the default from waitress' 4 to 8.
