Simplify activity monitoring by disabling it in lazygit project templates

Replace complex tmux hooks with targeted solution:
- Disable activity monitoring in basic.sh for git window (lazygit)
- Disable activity monitoring in research.sh for both code-git and paper-git windows
- Remove unreliable program detection hooks from tmux config
- Keep manual toggle (Ctrl+a A) for user control

This approach is simpler, more reliable, and directly addresses the root
cause of noisy activity notifications from project templates.
