chore(maven): refactor test suite and add analyzer tests

Remove non-functional test files (plugin.e2e.spec.ts, plugin.spec.ts, plugin.simple.spec.ts) and add comprehensive maven-analyzer.spec.ts with 10 tests covering Maven executable detection, platform-specific behavior, verbose mode, and error handling.
