Summary

• Add JS/TS config file support (dotswitch.config.ts, .js, .mjs, .cjs) using jiti for runtime transpilation
• Export defineConfig() helper for IDE intellisense and type safety
• Remove legacy .dotswitchrc.json support (breaking, but package is effectively unused at the moment)
• Replace toEqual with toStrictEqual across all tests

Config file resolution order

1. dotswitch.config.ts
2. dotswitch.config.js
3. dotswitch.config.mjs
4. dotswitch.config.cjs

Usage

// dotswitch.config.ts
import { defineConfig } from "dotswitch";

export default defineConfig({
  target: ".env.local",
  exclude: [".env.test"],
  hooks: { "main": "production" },
});

Test plan

• Typecheck passes
• All 135 tests pass
• Build succeeds
• Tested .ts, .js, .mjs, .cjs config loading
• Tested priority order, partial configs, invalid syntax fallback
