Pull request overview

This PR improves dyn-compatibility precision for the trait-contract must_be_object_safe analyzer by allowing method-level lifetime generics while continuing to flag type and const generics.

Changes:

• Refines object-safety generic detection with a new helper that only flags type/const method generics.
• Adds regression tests for lifetime-generic methods and const-generic methods.
• Bumps the crate version to 1.2.6 and updates changelog release notes.
