- entry.tsx no longer writes bootBanner() to the main screen before the
alt-screen enters. The <Banner> renders inside the alt screen via the
seeded intro row, so nothing is lost — just the flash that preceded it.
Fixes the torn first frame reported on Alacritty (blitz row 5 #17) and
shaves the 'starting agent' hang perception (row 5 #1) since the UI
paints straight into the steady-state view
- AlternateScreen prefixes ERASE_SCROLLBACK (\x1b[3J) to its entry so
strict emulators start from a pristine grid; named constants replace
the inline sequences for clarity
- bootBanner.ts deleted — dead code
