fix: builder-agent gotchas for incomingRefs, ViewHTML, workflow delete, project refresh, renderJinja2

[AutomateIP]

Summary

• Expanded gotcha docs(builder-agent): document JST step structure, Array callback methods, and Conditional.if...else #37 — incomingRefs stale cache causes the entire workflow to hang silently after workflow_start (not just evaluation failures). Fix: recreate via fresh POST instead of more PUTs.
• Added gotcha #44 — workflow delete endpoint: DELETE /workflow_builder/workflows/delete/{URL-encoded-name}. Documents correct endpoint vs the non-existent DELETE /automation-studio/automations/{id}.
• Added gotcha #45 — project component refresh pattern: remove all stale copies, re-add from standalone via components/add, update Operations Manager automation componentId to new UUID.
• Added gotcha #46 — renderJinja2 inline templates with \n store literal backslash-n in job_data, breaking downstream parse tasks. Use single-line templates.
• Added gotcha #47 — task outgoing can write directly to a job variable ("outgoing": {"merged_object": "$var.job.myVar"}). More reliable than a separate newVariable copy step and survives PUT cache issues.
• Added ViewHTML task JSON to the Manual Tasks section with all required fields (view, taskVersion: 2, hostApp) — omitting any one causes a draft validation error.

Test plan

• Verify gotcha docs(builder-agent): document JST step structure, Array callback methods, and Conditional.if...else #37 expansion accurately describes the hang-at-start symptom
• Verify new gotchas #44–47 do not conflict with existing content
• Verify ViewHTML JSON is syntactically correct and matches verified platform behavior
