Add end-to-end verification scripts and fix server issues

- Fix server hanging issue: incomplete HTTP responses in shttp.ts - Add proper JSON-RPC error responses per MCP specification - Fix PKCE challenge encoding: use base64url not standard base64 - Add comprehensive e2e scripts with OAuth flow and feature testing: - scripts/test-integrated-e2e.sh: Tests integrated mode - scripts/test-separate-e2e.sh: Tests separate mode - Scripts verify all README claims: 7 tools, 100 resources (paginated), 3 prompts - Add environment variable support and prerequisite checking - Add TODO documentation for Streamable HTTP implementation choices - Update README with table of contents and scripts documentation - Update project structure to include scripts directory Scripts successfully verify: ✅ Complete OAuth 2.0 + PKCE flows in both modes ✅ Token introspection and cross-server session management ✅ All MCP features working correctly ✅ README accuracy (tool/resource counts verified programmatically)

 - **Auth Tests**: OAuth flow and session ownership
 - **Multi-user Tests**: User isolation and access control
 
-### Additional Testing
+### Automated End-to-End Testing
+
+The `scripts/` directory contains automated test scripts that verify the complete OAuth flow and all MCP features:
+
+#### Scripts
+- **`test-integrated-e2e.sh`** - Tests integrated mode (MCP server as OAuth server)
+- **`test-separate-e2e.sh`** - Tests separate mode (external auth server)
+
+#### What the scripts test:
+- Complete OAuth 2.0 + PKCE flow from client registration to token usage
+- All MCP features: tools (7), resources (100 with pagination), prompts (3)
+- Session management and proper error handling
+- README claim verification
+
+#### Usage
+```bash
+# Test integrated mode
+./scripts/test-integrated-e2e.sh
+
+# Test separate mode 
+./scripts/test-separate-e2e.sh
+```
+
+**Prerequisites:** Scripts check for Redis and servers, providing setup instructions if missing.
+
+### Interactive Testing
 Use the MCP Inspector for interactive testing and debugging of OAuth flows, tool execution, and resource access.
