isAgentsJsonInvocation added to early-input bypass check

An agents-json invocation now also skips capturing early stdin at startup.

CLI startup now also checks isAgentsJsonInvocation alongside the existing MCP-serve, plugin-eval, and remote-control checks when deciding whether to start capturing early stdin input.

Anthropic's note

Upstream's own release notes for v2.1.257 name something this entry names, so the two are probably about the same change. Probably: the pairing is made on a shared name rather than on the words around it.
