v0.4.0

Added

• Select nested model profiles with --model <profile> or the top-level default_model/default-model config key, with inherited parent settings
• Put an instruction after a multi-line opening delimiter or enclose a same-line instruction in matching delimiters

Changed

• Use Escape instead of Space to cancel the current processing loop and report [user cancel received]
• Name dynamic command tools D<N> after their declaration line number
• Return both stdout and stderr from dynamic command tools
• Avoid returning already-known read_file lines until the file changes or an edit resets the task's read history
• Improve runtime tool-call output and show diffs for each successful edit_file call

Fixed

• Revert incomplete edits on stream errors instead of continuing marker cleanup
• Reliably remove complete multi-line marker spans, including decorated closing delimiters
• Preserve task markers and report an error when the agent makes no substantive edit
