Make the PROMPT_COMMAND chain with existing

aJanuary · aJanuary · commit 985e590c619c · 2025-10-30T09:32:58.000Z
If something else has already set the PROMPT_COMMAND (for example,
ghostty or mise), currently the themes will clobber the existing value,
breaking their functionality.

This patch adds `;$PROMPT_COMMAND` to the end, so that bash will execute
the existing commands as well.
