Salesforce connection recipe added to core — easier for the next person

[ZhixiangLuo]

What changed: A verified Salesforce recipe is now in tool_connections/salesforce/ — browser SSO, full REST API, SOQL and SOSL search, works on any org type.

Why it matters: Salesforce auth is non-obvious — connected apps are often disabled, SOAP login is being retired, and the Lightning session token does not work for API calls. This recipe handles all of that. Your agent does not have to figure it out.

What this means for you:

• Want to connect Salesforce: Run setup.md, select Salesforce — done in under a minute.
• Tool not listed here: Your agent can always use add-new-tool.md to connect any tool not yet in core — internal tools, custom dashboards, anything with a web UI or API.
