Sill v1.1.0

• Ghostty and cmux now get completions too, alongside Terminal.app, iTerm2 and VS Code.
• Commands the definitions don't cover can now be learned from their own help text — switch it on under Specs in Settings, and only real programs are ever run.
• Completing a word no longer leaves a space behind it, and the list closes so your next keystroke goes straight to the shell.
• When what you typed is already the whole word, Return runs the command instead of completing it.
• The list lines up with your cursor the same way in every terminal now.
• Arrowing to the top or bottom of a long list keeps the highlighted row clear of the edge instead of tucking it under.
• Fixed the stray characters that could appear at your prompt when a terminal answered slowly.
• Fixed the pale corners that showed around the popup.
