Pull request overview

This PR enhances the user experience by adding a chat tooltip that displays the keyboard shortcut for opening chat, and improves the app's UI presence by removing the dock icon (making it accessible only via the menu bar). The default keyboard shortcuts are updated from ⌘ I to ⌘ L for consistency.

Key changes:

• Added a chat tooltip that appears after 1 second when no code completion is active, showing the shortcut to open chat
• Changed default keyboard shortcuts from ⌘ I / ⌘ ⇧ I to ⌘ L / ⌘ ⇧ L
• Hid the dock icon by setting the app's activation policy to .accessory

The documentation example "⌘ L" is now accurate since the default shortcut was changed from "i" to "l". However, to avoid confusion, consider updating the example to use a generic key like "⌘ K" since "⌘ L" is now actually one of the default shortcuts in this codebase. This would make it clearer that it's just an example format.

Suggested change

	/// A string representation of the keyboard shortcut (e.g. "⌘ L").
	/// A string representation of the keyboard shortcut (e.g. "⌘ K").

When the delete key is pressed to clear the shortcut, the inputShortcut is first set to an empty string in the onKeyDown handler (line 133), but then when keyboardShortcut is set to nil (line 134), this onChange handler will immediately override it with the defaultValue.display (line 145). This means the user will see the default shortcut displayed instead of an empty field, which is confusing UX. The old code had the same behavior (it used an empty string), but now with the refactored code that always shows the default when nil, this creates an inconsistency. Consider checking if the new value is nil in the onChange handler and preserving the empty string in that case.

Suggested change

	inputShortcut = NSAttributedString(string: (newValue ?? defaultValue).display)
	if let shortcut = newValue {
	inputShortcut = NSAttributedString(string: shortcut.display)
	}

The phrase "instead of showing having a jaggy scrolling" is grammatically incorrect. It should be "instead of having jaggy scrolling" or "instead of showing a jaggy scrolling effect".

Suggested change

	// When changed, hide the tooltip instead of showing having a jaggy scrolling
	// When changed, hide the tooltip instead of having jaggy scrolling
