opencode's Edit tool sends camelCase input keys (filePath, oldString,
newString) and a plain-string success ack on output. The shared edit
schemas expect snake_case input and an object output, so calls fell
through to the generic "unknown" renderer (raw JSON Input/Output).
Normalize both at the opencode boundary so the quirk does not leak into
the cross-provider schema.
