Safe mode now shows in the agent list, survives job restarts and gets a generated exit hint

What

--safe-mode is a flag (an option added when starting Claude Code) that starts it with your customizations switched off, which helps when a broken setting is causing trouble. Several things about it changed:

• Agent list footer: the footer of the agents list now shows "safe mode" and "customizations are off" next to the waiting line. Before, only the waiting text appeared.
• Restarts: --safe-mode is now one of the flags carried over when a background job or session restarts. The warning about flags dropped on restart now reads "stripped respawnFlags token(s) that a restart does not re-apply" instead of calling them "non-allowlisted", and the saved flags go through an extra clean-up step.
• Exit hint: the hint telling you how to leave safe mode is now produced on the fly instead of always being the fixed text "restart without --safe-mode". Claude Code checks whether --safe-mode was on the command line, and the evidence includes the text "unset CLAUDE_CODE_SAFE_MODE", so the hint can point to the CLAUDE_CODE_SAFE_MODE environment variable as well. The matching hint for bare mode, which used to be the fixed text "restart without --bare", is built the same way.

Why

You can now see at a glance that a session is in safe mode, a background job started in safe mode stays in safe mode after it restarts, and the exit hint can reflect how safe mode was actually turned on.
