release: version 1.0.2 - Audit security fixes and RPM packaging

Security hardening:
- Add input sanitization for method (32), path (2048), host (256), http_version (16)
- Prevent log injection via oversized HTTP values
- Add LOG_THROTTLED macro for consistent error reporting
- Improve socket state double-check pattern to avoid unnecessary reconnects

Code quality:
- Fix const qualifier warnings in get_header()
- Add flags field to module definition
- Add -Wno-error=format-security for compatibility

Documentation:
- Clarify timestamp precision (microseconds expressed as nanoseconds)
- Update README and architecture.yml

Testing:
- Add 4 unit tests for input sanitization
- All 78 tests passing

Packaging:
- Remove DEB package support (RPM only: el8, el9, el10)
- Add CHANGELOG file included in RPM packages
- Bump version to 1.0.2
