This reverts commit 62dc0e7.

Updated the indentation in vercel.json to use tabs instead of spaces for improved consistency and readability. No functional changes were made.

Deleted the 'functions' section specifying the edge runtime for api/[...path].js in vercel.json. This simplifies the configuration and may reflect a change in deployment strategy or function location.

Switched all package 'resolved' URLs from a custom registry to the official npmjs.org registry. Also updated several dependencies to newer versions, including @cloudflare/unenv-preset, @cloudflare/vitest-pool-workers, @cloudflare/workers-types, @emnapi/runtime, and multiple @rollup/rollup platform-specific packages.

This commit removes all Vercel-specific files and configuration, including API handlers, configuration files, ignore files, and documentation references. Scripts related to Vercel deployment and development have also been deleted from package.json. The project is no longer intended to be deployed or run on Vercel.
