Option to disable tab title override

[katylava]

When I have multiple Claude sessions open for different projects (in separate tabs), the tab title override replaces my default tab title, which shows the directory. My default title uses a custom PWD truncation function, so this isn't something peon-ping could replicate — I just need the option to keep my own title.

Edit: Just realized I wasn't super clear -- the tabs with Claude show the directory, but not in the form I need them to identify my tabs easily. I have a custom function for that that sets my tab title.

Good call. The tab title override is nice for most people but steps on custom PS1/PROMPT_COMMAND patterns. A config knob like terminal_tab_title: false to opt out would be straightforward. The emit point is printf '\\033]0;%s\\007' in peon.sh — just skip when disabled. PR welcome.
