Marketplace onboarding, canvas loops, and SQL over spreadsheets

MagOneAI can now be bought on a cloud marketplace and used immediately, with no setup on our side.

Buyers self-onboard, creating a new org or attaching to one they already own, and the org's token quota is set from the plan they purchased. AWS is live today; Azure and GCP are in preview. Super-admins get a Marketplace page to enable each marketplace and map plans to entitlements.

On the canvas, we're introducing true loops. A conditional branch can point back to an earlier node to build an iterate-until-good region, with a loop budget and a forced exit branch when the budget runs out — no more unrolling the same nodes by hand.

Also in this release:

• Spreadsheet knowledge bases: CSV and XLSX files are queried with real SQL, so totals and averages are exact instead of the model's best guess
• Agents can ask a person: an agent stops mid-run, asks a named assignee, and resumes with the answer — first response wins across up to 50 people
• Prompt caching per agent: a cache TTL setting, cache-aware cost tracking, and a Cache Hit tile so you can see what you're saving

Notifications now actually fire. MCP server status, schedule changes, execution failures, and credential changes reach email and the in-app dropdown — the settings were always there, but nothing was ever sent.
