- ctx.SuspendTUI(callback): releases terminal for interactive subprocesses
(vim, shell, htop), automatically restores TUI when callback returns.
Uses BubbleTea v2 ReleaseTerminal/RestoreTerminal.
- api.RegisterMessageRenderer(config) + ctx.RenderMessage(name, content):
named render functions for branded/styled extension output. Renderers
receive content and terminal width, return ANSI-styled strings.
- ctx.ReloadExtensions(): hot-reloads all extensions from disk. Emits
SessionShutdown to old extensions, reloads source, emits SessionStart
to new. Event handlers, commands, renderers, shortcuts update immediately.
TUI command list refreshes via WidgetUpdateEvent. Extension tools are
NOT updated (baked into agent at creation, documented limitation).
New example extensions: interactive-shell.go, branded-output.go, dev-reload.go
