Add TestMain class covering the main() flow: asserts that _set_labels
is called with State/InProgress (and State/Ready removed) strictly
before _start_agent, and that no labels or agents are touched when
there are no ready issues.

Replace the tmux-based agent launcher with a direct subprocess.Popen
call. Claude sessions can't be attached to anyway, so the tmux layer
added complexity with no benefit. State now tracks a PID instead of a
tmux session name; liveness is checked with os.kill(pid, 0).

Previously claude was launched with -p (print mode) which produces no
visible TUI. Attaching to the session with `tmux attach -t issue-NNN`
showed a blank terminal. Removing -p makes Claude run its interactive
TUI inside the tmux pane, so the session is fully watchable.
Add scripts/test_agent_loop.py covering _start_agent command
construction and state file round-trips.
