feat!: Migrate the package to ESM

[mykola-mokhnach]

Summary

• Add "type": "module" and an exports map to package.json; keep main/types for compatibility.
• Explicitly set "module": "NodeNext" / "moduleResolution": "NodeNext" in tsconfig.json.
• Add .js extensions to all relative imports across lib/ and test/ (required by Node ESM resolution).
• Switch @appium/logger from a default import to the named log import in lib/devicectl.ts — @appium/logger is CJS-only, and under real Node ESM interop a default import binds to the whole module.exports object rather than unwrapping .default (unlike tsc's CJS-output interop shim). The old code would have thrown logger.debug is not a function at runtime; NodeNext module resolution caught this at build time.
• Add --enable-source-maps to the test/e2e-test scripts.

BREAKING CHANGE: Consumers using require('node-devicectl') muc import() — the package no longer ships a CommonJS entry
