Pull request overview

This PR fixes a bug where hints might not be properly resumed in the recover_signer_unchecked function when early returns occur. The fix implements an RAII (Resource Acquisition Is Initialization) guard pattern that ensures resume_hints() is always called via the Drop trait, even when the function exits early through multiple potential error paths.

Changes:

• Introduced a ResumeHintsGuard struct with a Drop implementation to ensure hints are resumed on all code paths
• Replaced manual cleanup code with RAII pattern in recover_signer_unchecked
• Updated zisk-related dependencies to commit acaaf0476a06f442a042d21fc3f41b27d03e703d and added lib-float dependency
