[Feature Request] Workflow commands flag

[AgustinSilverfin]

Describe the solution you'd like
We could introduce a --workflow, -w flag in most commands to perform operations in bulk, based on a pre-selection of common templates that are used together.

Additional context
We will need to introduce a new configuration file at the root of the repository, which could named workflows.json and look like:

"workflow_1": {
  "reconciliationTexts": [ "handle_1", "handle_2" ]
  "sharedParts": [ "handle_3", "handle_4"] 
}
"workflow_2": "..."

Scope update — the config half exists, in a different shape than proposed here.

What landed. Not a root workflows.json, but one file per workflow in a workflows/ folder — workflows/<handle>.json — read and validated in fsUtils.js#L489-L560 (getAllWorkflowHandles, getWorkflow, workflowAttributeProblems). Required shape:

{ "name": "...", "templates": { "reconciliations": [], "accounts": [], "exports": [] } }

What's still open.

• -w, --workflow reached only stats (bin/cli.js#L630), not "most commands" — nothing on update-*, create-* or run-test.
• No sharedParts key, which this issue explicitly asked for.

Worth retitling to the remaining work: extend the existing -w flag beyond stats and add shared parts to the schema.
