Module protocol 

Sidecar protocol types — line-JSON over stdio.

The host treats sidecars as lego-block processes: it starts them, sends generic trigger frames, and consumes generic status/text frames. Plugin semantics live entirely outside core.

Wire format: one JSON object per line on the sidecar’s stdin/stdout.

Enums

InsertTextMode

How text emitted by a sidecar should be applied to the input buffer.

SidecarCommand

Commands sent from Synaps CLI to the sidecar (one per line, JSON).

SidecarFrame

Frames emitted by the sidecar (one per line, JSON).

Constants

SIDECAR_PROTOCOL_VERSION
