fix: make package exports loadable in Node

[nrps9909]

Summary

• make the generated es build directly loadable by native Node ESM by rewriting relative specifiers to explicit .js or /index.js targets
• emit es/package.json with "type": "module", while keeping CommonJS require mapped to the existing lib build
• verify all 13 public root, generate, interface, locale, and compatibility entry points through both import() and require(), including their public export keys and representative default values

This preserves the package's native ESM export shape instead of routing Node import through CommonJS interop. The rewrite resolves against the generated files, fails on an unresolved relative specifier, and is idempotent.

Closes #1002.

Verification

• reproduced the baseline failure from an unmodified packed master package on Node 24.15.0: importing @rc-component/picker/locale/en_US raised ERR_MODULE_NOT_FOUND for es/locale/common
• npm run compile: 148 ESM files built and 233 relative specifiers rewritten on the first pass
• repeated node scripts/rewrite-esm-imports.js: 0 rewrites, confirming idempotency
• npm run test:node-exports: all 13 exported entry-point variants loaded through ESM import() and CommonJS require(), with matching public keys and correct root, generate-config, and locale default values
• installed the patched tarball into fresh ESM and CommonJS consumers: root, generate, canonical locale, /lib locale, and /es locale imports all passed without nested CommonJS defaults
• scanned all 148 generated ESM JavaScript files: no extensionless relative module specifiers remained
• npm test -- --runInBand: 15 suites passed, 468 tests passed, 2 skipped, 29 snapshots passed
• focused ESLint for both scripts, Prettier, and git diff --check

npm run lint:tsc still reports the existing Jest matcher typing errors in unchanged tests/picker.spec.tsx (toBeCalled*); the same failures reproduce on the PR base, and this patch does not touch source or test TypeScript.

AI assistance disclosure: Codex was used to trace package resolution and CommonJS interop, build the tarball reproduction matrix, implement the build rewrite and export-shape assertions, and run the validation above. The failure and passing results were verified locally against the cited commits.

Walkthrough

本次变更新增 es 构建后的 ESM 导入重写脚本，并为 es 目录声明模块类型。导出映射移除子路径中的 node 条件。发布前流程继续验证多个入口点的 CommonJS 与 ESM 加载结果。

Changes

Node ESM 构建与导出验证

Layer / File(s)	Summary
es 构建导入重写 scripts/rewrite-esm-imports.js	脚本递归处理 es 目录中的 JavaScript 文件，为相对模块说明符补全 .js 或 /index.js，并写入 es/package.json 的 type: module 声明。
导出映射与入口验证 package.json, scripts/test-node-exports.js	导出子路径移除 node 条件。新增验证脚本，使用 require 和动态 import 加载多个入口点，并检查导出键及指定导出值。
编译与发布接入 package.json	compile 在 father build 后执行 ESM 导入重写。prepublishOnly 保留编译后的 test:node-exports 检查。

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 13028

The PR makes the generated ESM package loadable by native Node while preserving CommonJS behavior, with entry-point, build, packaging, and regression checks passing. No actionable merge-blocking risk remains beyond normal checks and review.

🔧 ESLint

If the error stems from missing dependencies, add them to the package.json file. For unrecoverable errors (e.g., due to private dependencies), disable the tool in the CodeRabbit configuration.

ESLint install failed: private package registry requires authentication. Disable ESLint in CodeRabbit settings or use public packages.
