fix: use static import for proxy-agent to fix Bun single executable bundling

[Copilot]

proxy-agent was wrapped in dynamicNodeImport() to hide it from browser bundlers, but this also prevents Bun (and similar tools) from statically discovering it when compiling single executables — causing a runtime Cannot find package 'proxy-agent' error.

Changes

• src/http_client.ts: Replace dynamicNodeImport('proxy-agent') and dynamicNodeImport('node:os') with static top-level imports. proxy-agent is now statically discoverable by all bundlers targeting Node.js.
• rsbuild.config.ts: Add resolve.alias: { 'proxy-agent': false } to exclude proxy-agent from the browser bundle (replaced with an empty stub). The existing isNode() guard in initNode() ensures ProxyAgent is never invoked in browsers.

The dynamicNodeImport helper is retained in utils.ts — it's still used for node:util/node:zlib in maybeGzipValue.

This section details on the original issue you should resolve

<issue_title>Dynamic import of proxy-agent breaks bun single executable bundling</issue_title>
<issue_description>Source code:

import { ApifyClient } from 'apify-client';

const client = new ApifyClient({
	token: process.env.APIFY_TOKEN,
});

const me = await client.user('me').get();

console.log(me);

Running like this works: APIFY_TOKEN="apify_api_you_wish" bun src/index.ts

Building into a single executable like so: bun build src/index.ts --target node --compile --outfile apifyclient followed by running it does not, and throws error: Cannot find package 'proxy-agent' from '/$bunfs/root/apifyclient'

In apify-cli I had to basically build bundles in 2 steps:

1. single file executable that manually imports proxy-agent by adding in a import {} from "proxy-agent"
2. patch the result to reference the manual import.

See the diff from the PR</issue_description>

<agent_instructions>Try implementing the fix ideated in the last comment. Make minimal changes to achieve the result. Add minimal comments, only if something is really hard to understand. use conventional commits for commit messages and PR title.</agent_instructions>

Comments on the Issue (you are @copilot in this section)

@barjin I believe this is essentially the same as #852 . The current setup doesn't expect the use of bundlers with Node environments.

Perhaps we can update the bundling setup (the one here, generating ./bundle.js), so it drops the isNode() blocks altogether, but keeps the imports discoverable when importing apify-client (not apify-client/browser).</comment_new>
