Keep Orca CLI first after shell startup (#25130)

* Restore the owning Orca CLI path after shell profiles

* Use a literal marker for the Bash lookup regression

* Preserve plain panes and initialize zsh after prompt hook replacement

* Preserve user line-editor dispatchers during deferred startup

* fix: retain CLI startup when global Zsh replaces prompt hooks

* test: replay global Zsh hook replacement after host startup

* test: isolate controlled Zsh widgets from distro keyboard setup

* fix(shell): preserve user hooks during deferred zsh initialization

* Keep completed Zsh startup hooks retired when the wrapper is sourced again
