Adds a new skill for Salesforce Flow Approval Processes
(processType: ApprovalWorkflow), a distinct flow type not covered
by the existing generating-flow skill.
Key contributions:
- Full architecture guide: orchestration, Background Steps, Approval
Steps, Screen Flows, WebLink trigger, Lightning page components
- Explicit delegation rule: AutoLaunched and Screen Flows are generated
via the generating-flow MCP pipeline; only the ApprovalWorkflow
orchestration XML is written manually
- Hard-stop constraints mapped to known deployment/runtime errors
- XML reference patterns in references/xml-patterns.md
- Common errors quick reference table with root causes and fixes
- Required deployment order to avoid dependency failures
