From: Hetvi Thakar <hthakar@cisco.com>

Backport the upstream prompt-handling fix [1] identified by advisory
[3]. Preserve literal prompts across Bash compatibility modes and
leave PS1 unchanged in unsupported POSIX shells.

Include follow-up [2], identified by advisory [4], so later prompt
option changes and child shells cannot execute the stored prompt.
This also fixes CVE-2026-115586, a regression in the initial fix.
Keep only the required Bash/Zsh security changes and regression tests.
