Pull request overview

This PR fixes a critical issue where Cloudflare Wrangler fails when project names contain dots, underscores, or other invalid characters. The solution adds a sanitization function that transforms project names from package.json to comply with Wrangler's strict naming requirements (alphanumeric lowercase with dashes only).

Key Changes:

• Introduced sanitizeWranglerName() utility function that normalizes project names to Wrangler-compatible format
• Applied sanitization to the Cloudflare adapter when generating wrangler.jsonc configuration
• Added comprehensive unit tests covering edge cases like dots, Unicode characters, length limits, and invalid inputs
