Subject: [PATCH 1/8] Add FileParserPlugin example for AI SDK v5

- Add PDF fixtures (small, medium, large, xlarge) with verification codes
- Create comprehensive file-parser example testing all PDF sizes
- Uses AI SDK's file attachment format with automatic plugin enablement
- Validates extraction of verification codes from PDFs

+# OpenRouter FileParserPlugin Examples (AI SDK)
+
+Examples demonstrating OpenRouter's FileParserPlugin with AI SDK v5.
+
+## Overview
+
+The FileParserPlugin is automatically enabled when using file attachments with the AI SDK provider. It:
+
+- Processes PDFs sent via data URIs
+- Extracts text using server-side parsing
+- Integrates seamlessly with AI SDK's message format
+
+## Examples
+
+- `file-parser-all-sizes.ts` - Tests PDF processing across multiple file sizes
+
+## Running
+
+```bash
+bun run typescript/ai-sdk-v5/src/plugin-file-parser/file-parser-all-sizes.ts
+```

Subject: [PATCH 2/8] Add shared fixtures module and JSON metadata

- Update AI SDK example to use shared fixtures from pdf-example-fetch
- Use absolute paths so examples work from any directory
- Read verification codes from JSON metadata (inherited from parent branch)
- Add file-parser-pdf-url.ts example
