v0.2.9

• Fixed the message composer being a single-line input that couldn't actually hold a multi-line message — Enter always sent immediately with no way to insert a line break, and pasting multi-line text (like a script) had its line breaks silently stripped. This made the v0.2.7 code-block feature unreachable in practice. Now Enter sends and Shift+Enter adds a line break, and the composer grows with your message as you type.
