feat: add edgeone adapter

[zhxycn]

Add EdgeOne Pages adapter for deploying Elysia applications to Tencent Cloud EdgeOne Pages Node Functions.

Features

• Extends WebStandardAdapter for EdgeOne compatibility
• Exposes EdgeOne context (clientIp, geo, uuid, region) to route handlers
• Provides createEdgeOneHandler() for exporting EdgeOne-compatible handlers
• Plugin compatibility (tested with @elysiajs/swagger)

Usage

// node-functions/api/hello.js
import { Elysia } from 'elysia'
import { EdgeOneAdapter, createEdgeOneHandler } from 'elysia/adapter/edgeone'

const app = new Elysia({
  adapter: EdgeOneAdapter,
})
  .get('/api/hello', (context) => {
    return {
      message: 'Hello EdgeOne',
      clientIp: context.clientIp,
      geo: context.geo,
      uuid: context.uuid,
      edgeoneServer: context.edgeoneServer
    }
  })
  .compile()

export const onRequest = createEdgeOneHandler(app)

If this PR is merged, I will create corresponding documentation at https://github.com/elysiajs/documentation.

Testing

Successfully tested on EdgeOne. Screenshots below.

Note: Without a custom domain, clientIp and geo are not available. I tested with my own domain, and the IP shown in the screenshot is from a proxy to demonstrate the geo-location feature.

Walkthrough

This pull request introduces EdgeOne adapter support for Elysia. It adds a new export in package.json, implements an EdgeOne adapter with context handling and handler creation, and includes comprehensive test coverage for the new adapter integration.

Changes

Cohort / File(s)	Summary
Package Configuration package.json	Adds new export entry for ./adapter/edgeone with types, import, and require paths pointing to built distribution files.
EdgeOne Adapter Implementation src/adapter/edgeone/index.ts	Introduces EdgeOneContext interface, EdgeOneAdapter constant, and createEdgeOneHandler function. Captures EdgeOne-specific request properties (uuid, params, env, clientIp, geo, server) and exposes them on Elysia context. Handler validates app compilation before delegating to app.fetch.
EdgeOne Adapter Tests test/adapter/edgeone/index.test.ts	Comprehensive test suite covering basic request handling, route parameters, context properties, POST/GET/query operations, 404 behavior, HTTP method routing, and compilation validation.
