v0.13.0

Copy chat text with a plain left-click drag: highlight any passage in the transcript and it is copied to the clipboard when you release the mouse — no Shift or copy shortcut needed. Selection works in either direction, across messages, and with code blocks and Unicode text; soft-wrapped lines copy without artificial newlines, and code indentation and logical line breaks are preserved. Chat labels and controls are excluded. While dragging, displayed messages stay stable even if the answer is still streaming. Move to a transcript edge to scroll farther, or use the mouse wheel. Escape, resizing, or switching Sessions cancels a selection. Ordinary controls now activate on click release rather than press, so starting a drag never triggers them. A failed clipboard write shows an error notice. This release carries a small maintained extension of the Breeze TUI library (vendored under vendor/breeze with attribution) to support complete pointer gestures; it will be retired when upstream exposes an equivalent interface.
