- Task Documents right pane gains in-place editing with the shared CodeMirror
FileEditor (Save via PUT /tasks/:id/documents/:key); task documents now
render markdown by default.
- Project Files pane is editable the same way via the project workspace file
API, replacing the Read-only badge contract.
- Fix "Add comment" doing nothing again: `.selection-comment-trigger:active`
tied the global `.btn:active` at (0,2,0) and lost to a bundle-order flip,
teleporting the trigger mid-press so click never fired. `:active` rules now
use `.btn.selection-comment-trigger` (0,3,0); regression test asserts the
prefix so a plain-selector revert fails.
- Align the task-document header: path box and Plain/Edit (Cancel/Save)
actions share one row, meta line sits below.
