ci: deploy virtool.ca via Cloudflare Workers

[igboyes]

Summary

• Adds wrangler.jsonc configuration to deploy the static Astro site as a Cloudflare Worker with proper asset handling and trailing-slash normalization
• Adds wrangler as a dev dependency and introduces deploy and preview npm scripts that build then run via Wrangler (original Astro preview preserved as preview:astro)

Test plan

• Run npm run build to confirm the site builds without errors
• Run npm run preview and verify the site is served correctly via Wrangler locally
• Run npm run deploy and confirm the site deploys to Cloudflare Workers
• Verify 404 pages and trailing-slash redirects work as expected on the deployed worker

Code Review

This pull request integrates Cloudflare Wrangler into the project to facilitate deployment and local previewing of built assets. Key changes include adding wrangler to the development dependencies, updating the preview script, and adding a new deploy command in package.json. Additionally, a wrangler.jsonc configuration file has been introduced to define the project's asset handling and compatibility settings. There were no review comments provided, and I have no further feedback on these changes.
