chore: bump to 0.3.4 and patch acadrust to fix/hatch-boundary-handle-cap

The acadrust fix from https://github.com/hakanaktt/acadrust/pull/27
unblocks files with corrupt hatch boundary-handle counts (anteen.dwg
went from >100 s "stuck" to ~0.7 s release). Until the PR lands on
upstream/main, [patch.crates-io] points at the fork branch carrying
that commit; the comment in Cargo.toml notes the revert.
