Save a new version of a workflow

Never overwrites: every save is a version, and what runs does not change until a person activates one.

Send baseVersion (the latest version when you read it) to be refused with 409 if somebody saved since. The answer is the compiler’s verdict on this version: ok, every error with its line and the fix, warnings, the graph the Automations tab draws and what the workflow can touch. A version that does not compile is kept and cannot be activated: fix the errors and save again.

Requires the scopes workflows:write, records:read, records:write, schema:read. Operation workflows.code.set. MCP tool workflows_code_set. CLI: grid82 workflows code set (npx grid82).
