fix: AI terminal init, Shift+Tab nav, code block rendering, command filtering

- Fix AI terminal not initializing (wait for shell col visibility, remove offsetHeight guard)
- Add Shift+Tab to cycle between shell terminals
- Handle unclosed code blocks in renderContent (Shell + Studio)
- Filter irrelevant commands from history (short/non-alpha backend + expanded frontend exclude list)
