Migrate test suite from ava to Node.js built-in test runner

[mjradwin]

Replace the ava test framework with Node.js's built-in node:test module and node:assert for assertions.

Changes

• Test framework: Migrated from ava to Node.js built-in node:test

  • Updated all test declarations from test(name, (t) => {...}) to test(name, () => {...})
  • Removed the t parameter from all test callbacks

• Assertions: Replaced ava assertion methods with Node.js assert equivalents

  • t.is() → assert.strictEqual()
  • t.true() → assert.ok()

• Dependencies: Removed ava from devDependencies in package.json

• Test command: Updated npm test script from ava to node --test

This change simplifies the test infrastructure by using Node.js's native testing capabilities, eliminating an external dependency while maintaining full test coverage and assertion semantics.
