esm.sh's build backend was returning HTTP 500 for unbuilt @codemirror/*@6
version ranges (out of disk). A failed top-level module import aborts the
whole <script type=module>, so fillLangs()/loadModels() never ran and the
language/model dropdowns came up empty despite a healthy backend.
- Pin CodeMirror imports to already-built versions (view@6.36.0,
state@6.7.0, commands@6.10.4), which esm.sh serves fine during the outage.
- Remove vim editing mode entirely (@replit/codemirror-vim import, vim()
extension, Vim.mapCommand H/L bindings, .cm-vim-panel CSS). The
document-level Shift-H/L focus cycling is retained.
- Bump to 0.4.0.
