Show agterm in the menu bar

A proper Mac app should have a menu bar, thinking out loud about what could be there to be useful:

Notification Indicator aka "Needs Attention"

on "a proper Mac app should have a menu bar item" I'd push back a little, plenty of good Mac apps skip it, so it's not a must-have. But as an option, off by default, it's a reasonable idea.

the thing that actually earns it a spot: the agent-status attention (blocked/completed) is the one signal with no always-visible home once agterm isn't frontmost. The sidebar glyph and the titlebar bell live inside the window, and the Dock badge tracks the notification unseen-count, which is a different thing, a session status blocked bumps no Dock badge and posts no banner. So a menu-bar item is the natural home for that ambient "something's waiting" state, with a dropdown to jump straight to it.

visually I'd base it on the app icon, monochrome (a template glyph), and show "needs attention" by filling or tinting it, same idea as the titlebar bell going bell to bell.fill when something's blocked.

implementation is mostly a thin MenuBarExtra over the attention set plus the existing cross-window reveal (the notification click already does the jump). The one real decision is lifecycle: agterm quits after the last window closes, so a menu-bar presence needs a call, keep the process alive while it's enabled, or only show the item while at least one window is open.

common, this was an obvious bait!

Idle:

Completed:

Blocked:

Menubar item is opt-in, disabled by default. If the setting is enabled, keep agterm alive after the last window closes. That matches user expectation for a menu bar monitor: “I enabled this because I want ambient attention even when no window is frontmost.” If it disappears when the last window closes, it is less of a monitor and more of a window accessory.

well, my helpful silicon friend doesn't have a sense of humor and is skilled at "Decline first if a good reason" ;)

about glyphs - I'm not sure why we even care about the number here; it will trigger user clicks anyway, and the menu will show all the details. My vote is just to colorize it accordingly and keep it uniformed
