Address deprecation warnings for 8.5

This PR addresses deprecation warnings for PHP 8.5

[Copilot]

Pull request overview

This PR aims to eliminate (and prevent regressions of) PHP 8.5 runtime deprecations by removing deprecated calls (curl_close(), Reflection*::setAccessible()), replacing reflection-based access with proper accessors, and adding unit tests to guard against reintroduction.

Changes:

• Replace reflection-based option “mode” extraction with public-API reconstruction in OptionReuseTrait.
• Stop calling deprecated APIs (curl_close(), setAccessible()), using unset()/accessors instead.
• Add unit tests: a static deprecation scan for src/, and behavior tests for OptionReuseTrait.
