Summary

Gemini 2.5 Flash as primary AI provider with Claude Haiku as fallback, behind a unified AIProvider abstraction (ai_provider.py)
AI-powered auto-fix for validation errors — "Fix with AI" button in the tree editor's validation panel generates structural fixes using AI, with a review modal for applying each fix
Migrated existing AI tree generator from direct Anthropic SDK calls to the new provider abstraction

New env vars for deployment

Variable	Default	Notes
`AI_PROVIDER`	`gemini`	`"gemini"` or `"anthropic"`
`GOOGLE_AI_API_KEY`	—	Required for Gemini (falls back to Anthropic if missing)

Backend changes

ai_provider.py — GeminiProvider + AnthropicProvider + get_ai_provider() factory with fallback
ai_fix_service.py — Builds targeted prompts per failing node (full tree outline + node detail + error), validates fix by substituting into tree copy, retries once with corrective prompt
POST /ai/fix-tree endpoint — rate limited (10/min), requires engineer role
ai_fix.py schemas — Request/response Pydantic models
Refactored ai_tree_generator_service.py to use provider abstraction
Config: AI_PROVIDER, GOOGLE_AI_API_KEY, AI_MODEL_GEMINI, AI_MODEL_ANTHROPIC

Frontend changes

"Fix with AI" button in ValidationSummary (appears when there are fixable structural errors)
AIFixReviewModal — before/after JSON diff per fix, Apply/Skip per fix, Apply All
TreeEditorPage orchestrates the flow: validate → fix → review → apply → re-validate

Test plan

639 backend tests pass (including 47 new AI-specific tests)
Frontend build passes clean
Set GOOGLE_AI_API_KEY in Railway Shared Variables
Verify AI Flow Builder still works with Gemini provider
Create a flow with validation errors, click "Fix with AI", verify fixes are proposed and can be applied
