Bash shell integration makes script execution slow

[ZoltanLajosKis]

Script execution with shell-integration takes a lot longer than with shell-integration = none.

Executing time for i in {0..100000}; do :; done takes around 150 ms when disabled, and takes over 4 seconds when not disabled.

Executing time for i in {0..100000}; do echo $i; done takes around 450 ms when disabled, and takes over 6 seconds when not disabled.

Tested on Ubuntu 22.04.5 with X11, running Ghostty 1.0.0 built with zig-0.13.0 (--release=fast), default config.

I have an upstream bash-preexec change under consideration that should improve this by removing per-prompt history | sed command overhead: rcaloras/bash-preexec#167 (comment)
