• Rework Ctrl+C to interrupt first and exit on a second press, with Escape now clearing the input bar.
• Add an input prompt indicator, child-agent keybinding hints, and OS-specific shortcut labels.
• Surface a clean warning when ripgrep is missing and keep kernel diagnostics out of the TUI.
• Stop blocking on IPython kernel startup and fix the subagent tool-expansion shortcut.
• Tone down the Prime theme's neon colors and keep browser sign-in links usable without terminal hyperlinks.
