fix: remove whitespace before semicolon in browser.js and fix CITGM packaging issues

[abhayagarwal-dev]

Issue

A stray space before the semicolon at src/browser.js:222 causes a semi-spacing lint error, making npm run lint exit non-zero and failing CITGM runs on s390x (Node.js v20.11.0).

src/browser.js:197:4

Fixes

• src/browser.js:222 : Remove stray space before semicolon to fix the semi-spacing lint error
• package.json (files) : test.js and test.node.js were not included in the published tarball; CITGM installs from the tarball so mocha had no test files to run, causing an immediate failure
• package.json (test script) : test:browser requires a Chrome binary; on headless environments like s390x, karma launches and hangs indefinitely waiting for a browser connection. Browser tests remain available via npm run test:browser

    ✓ passes a basic sanity check
    ✓ allows namespaces to be a non-string value
    ✓ honors global debug namespace enable calls
    ✓ uses custom log function
    extend namespace
      ✓ should extend namespace
      ✓ should extend namespace with custom delimiter
      ✓ should extend namespace with empty delimiter
      ✓ should keep the log function between extensions
    rebuild namespaces string (disable)
      ✓ handle names, skips, and wildcards
      ✓ handles empty
      ✓ handles all
      ✓ handles skip all
      ✓ names+skips same with new string
      ✓ handles re-enabling existing instances
