Error messages that previously said "in a background session" now say "no terminal is attached to this background session" and include instructions on how to attach. Three affected messages:
- MCP server authentication: "Can't authenticate MCP servers while no terminal is attached to this background session. Attach to it and try again."
/install-github-app: "Can't run /install-github-app while no terminal is attached to this background session. Attach to it and run the command again."/mcppanel: "Can't open MCP settings while no terminal is attached to this background session. Attach to it and run /mcp again, or use \/mcp enable|disable|reconnect <server>\to steer without the panel."
Evidence
Background session guards (search for "no terminal is attached to this background session")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
