Splash screen auto-dismisses too quickly — used to persist until user input

Description

The Claude Code CLI splash screen now flashes for less than a second and auto-dismisses. Previously, it would persist on screen until the user chose to dismiss it.

Expected behavior

The splash screen should remain visible until the user dismisses it (press a key / start typing), as it did in earlier versions.

Actual behavior

The splash screen appears for a fraction of a second and then disappears automatically, making it impossible to read.

Environment

• Claude Code version: 2.1.56
• OS: macOS (Darwin 25.3.0)
• Shell: zsh
• Terminal: Standard terminal (not IDE-embedded)

Notes

This is the opposite of #8437 (which requested an option to disable the splash screen). In this case, the splash screen is wanted but disappears too fast to be useful.
