Add Local Development Environment Variables, fix bugs, improve UI

- Introduced a new `.dev.vars` file to define local development environment variables, specifically overriding the `R2_PUBLIC_URL` for local testing.
- Made adjustments in `wrangler.toml` to clarify the usage of `R2_PUBLIC_URL` in different environments.
- Updated documentation to reflect changes in local development setup and AI Gateway integration.

+## Stagehand Integration
+
+Stagehand (used in TestAgent for browser automation) routes all AI requests through AI Gateway:
+
+```typescript
+// In TestAgent.ts
+const llmClient = new WorkersAIClient(this.env.AI, {
+  gateway: {
+    id: 'ai-gateway-gameeval'
+  }
+});
+
+const stagehand = new Stagehand({

+  llmClient,
+  // ... other options
+});
+```
+
+All `observe()` and `act()` calls made by Stagehand now route through AI Gateway, providing:
+- Full observability of Stagehand's AI usage
+- Request caching for repeated patterns
+- Cost tracking for browser automation AI calls
+- Unified monitoring across all AI providers

+## Complete AI Gateway Integration Status
+
+All AI calls in the system now route through AI Gateway (`ai-gateway-gameeval`):
+
+### ✅ Workers AI Calls (Primary Provider)
+
+1. **Stagehand Browser Automation** (`WorkersAIClient`)
+   - Location: `src/shared/helpers/workersAIClient.ts`
+   - Routes through: Gateway config passed to `this.binding.run()`
+   - Used by: TestAgent phases (observe/act calls)
+   
+2. **Direct AI Helper** (`callAI()` → `callWorkersAI()`)
+   - Location: `src/shared/helpers/ai-gateway.ts`
+   - Routes through: Gateway config passed to `env.AI.run()`
+   - Used by: Phase 4 evaluation, any direct AI requests
+
+### ✅ OpenAI Calls (Fallback Provider)
+
+3. **OpenAI Fallback** (`callAIGatewayOpenAI()`)
+   - Location: `src/shared/helpers/ai-gateway.ts`
+   - Routes through: `https://gateway.ai.cloudflare.com/v1/{account}/{gateway}/openai/...`
+   - Used by: Automatic fallback when Workers AI fails
+
+### Gateway Configuration
+
+**Gateway Name**: `ai-gateway-gameeval`  
+**Account ID**: `a20259cba74e506296745f9c67c1f3bc`
+
+All requests include gateway metadata in logs for tracking:
+```json
+{
+  "provider": "workers-ai",
+  "model": "@cf/meta/llama-3.3-70b-instruct-fp8-fast",
+  "gateway": "ai-gateway-gameeval",

-- The live feed and Timeline are very similar.
-- Do we really need to hot reload with polling?

+**Implementation Plan:**
+- Story 3.5 is a validation story - no code changes required
+- All system components exist from previous stories (Dashboard Worker, TestAgent DO, Workflow, D1, R2, Browser Rendering, AI Gateway)
+- Validation approach: Manual QA testing with real DOM-based games
+- Deliverables: Test plan document, edge cases documentation, validation findings
+
+**Preparatory Work Completed:**
+1. Created comprehensive test plan: `docs/validation/test-plan-story-3-5.md`
+   - Includes 11 task checklists matching story acceptance criteria
+   - Provides input schema example for AC 9
+   - Includes SQL queries and wrangler commands for validation
+   - Includes results tracking tables for all validation activities
+2. Created edge cases documentation: `docs/validation/edge-cases-epic-3.md`
+   - Template for documenting bugs and edge cases
+   - Categorized by priority (P0-P3) and component
+   - Includes recommendations for Epic 4 prioritization
+
+**Manual Validation Required:**
+- Adam needs to identify 3-5 DOM-based game URLs (different genres, control schemes)
+- Execute validation tests per test plan checklist
+- Deploy or run dashboard worker locally to test submissions
+- Query D1 database to verify data integrity
+- Check R2 storage for screenshot and log evidence
+- Document any issues discovered in edge cases file
+- Update sprint-status.yaml with validation findings
+
+**Story Status:**
+- Preparatory tasks (Task 1 partial, Task 11 partial): Complete
+- Manual validation tasks (Tasks 2-10, remaining subtasks): Require user execution
+- Story marked "in-progress" in sprint-status.yaml
