Subject: feat(launcher): add ai --runtime for choosing the agent CLI

The ai launcher can now start codex sessions: --runtime claude|codex (or AI_RUNTIME), a runtime-to-CLI map with local reserved behind a clear error until the local-model evaluation picks a CLI, and a runtime-aware dependency check. A new --print-launch mode prints the pane launch command without touching tmux or fzf, and is the seam the six new bats tests drive. Both current CLIs take the opening line as a positional prompt, so only the command name varies.

+# The ai launcher's --runtime flag: pick the agent CLI (claude, codex) that
+# a project window launches. Part of the generic-agent-runtime arc — the
+# tmux-side counterpart of .emacs.d's ai-term multi-LLM handoff. The
+# --print-launch mode exists for exactly these tests: it prints the launch
+# command a real run would send to the pane, without touching tmux or fzf.
