rexmod v0.1.0

First release.

Added

• Changes panel on the right of the Rex window: Last Turn, Uncommitted and Branch change sets, and a Files tab, styled like Rex's own sidebar. ⌘⇧E shows or hides it; the toggle sits with the pane actions.
• Editor pane: click a file and it opens in Neovim next to your agent, at the changed line; one editor per tab.
• Review comments: <Space>r on a line or selection in the editor; they reach the agent with your next message, or right away from the panel.
• ⌘P file picker over the agent's repository, with the editor's syntax highlighting in the preview.
• Works with every agent Rex supports: Claude Code and Codex (hooks), OpenCode (plugin), Pi (extension). With several agents in a tab the panel follows the one you focused last.
• Language support on demand in the editor: open a file and its tree-sitter parser and language server are installed and started.
• Installer for a clean Mac, an uninstaller, and a LaunchAgent that re-applies the patch after Rex updates itself.
