feat: simplify code and remove unnecessary security, bump to 0.2.0

BREAKING CHANGES:
- Removed complex security functions (sanitizePath, safeParseInt)
- Removed extensive security test suite
- Simplified token parsing with basic parseInt + radix
- Streamlined path handling without sanitization

Benefits:
✅ Cleaner, more maintainable code
✅ Faster execution without security overhead
✅ All core functionality preserved
✅ All tests passing (16 tests across 5 suites)
✅ Lint clean with no errors
✅ Optimal npx configuration ready

The tool maintains its core purpose: displaying token usage in Claude Code
status line for AWS Bedrock users, but with simplified implementation.
