[FAQ] Add: large content handling in custom safe output jobs

[chrizbo]

Adds a FAQ entry explaining the [Content too large, saved to file: ...] placeholder that appears in custom safe output jobs when the agent passes large bodies to a safe output tool, and provides the resolveBody() helper pattern for resolving it.

Source issue: github/agentic-workflows#491

Change type: New FAQ entry

What was added: A new Q&A under the "Workflow Design" section of the FAQ covering:

• Why the placeholder appears (MCP Gateway offloads large content >~16,000 tokens to a file)
• The placeholder string format
• A resolveBody() JavaScript snippet custom job authors can use
• Guidance on the 65,000-character built-in handler limit
• A note about alternative approaches for very large content
