Get or seed instructions

This is a read call: the response body carries the instructions text, not the request. It is a POST rather than a GET only so default can be sent in the body (starter prompts are far too long for a query string).

If the doc is missing and default is provided, that default becomes version 1 (source: seed) and is returned, so a shipped template works with zero setup. If it is missing and no default was sent, you get a 404.

When the doc already exists, default is ignored and the stored text always wins - editing a prompt in the dashboard is never overwritten by the automation. To change the stored text, use POST /api/instructions/versions instead.

curl -X POST "https://example.com/api/instructions" \  -H "Content-Type: application/json" \  -d '{    "project": "Customer Support",    "task": "Email reply",    "default": "You write friendly, concise replies to customer emails. Never promise a refund date you cannot keep."  }'

{  "projectName": "string",  "taskName": "string",  "content": "string",  "version": 0,  "updatedAt": "2019-08-24T14:15:22Z",  "hasPendingSuggestion": true}
