fix: ensure terminal properly resizes after startup script failure

This change fixes a bug where the web terminal doesn't fit the screen properly
when a startup script fails, causing text at the bottom of the terminal to be
hidden. The solution adds a delayed second call to fitAddon.fit() after alert
changes to ensure proper terminal sizing.

Fixes #46
