CLI 0.16.0 — Machine-readable --json across every command

Every mf data and mutation command now supports --json, so you can script Manyfold end to end and parse both success and failure reliably.

Highlights

• --json everywhere. All data and mutation commands accept --json for machine-readable output; deletes emit { "ok": true, "id": ... }.
• Parseable errors. In --json mode, failures print { "error": { "message": ... } } on stderr with a non-zero exit, so scripts can branch on both outcomes.
• Secrets stay redacted. Channel output remains secret-redacted in JSON mode, and login --json reports the result without ever printing your token.

Notes

• Raw-stream and interactive commands (files read, daemon logs, daemon start/register/stop, update) keep their existing behavior.
