feat(loop): add support for non-zero first-window tmux configs

Browse source 
Fixes tmux targeting for users with custom base-index configuration.

Changes:
- Add get_tmux_base_index() to detect tmux window base-index setting
- Replace hardcoded :0 window references with dynamic ${base_win}
- Handles configurations like 'set -g base-index 1'
