PR Review ✅

Summary: Safe dependency update from anthropic 0.76.0 to 0.77.0

Code Quality: ✅ Clean version bump in pyproject.toml and lock file

Breaking Changes: ✅ None affecting this codebase

• SDK migrated output_format to output_config, but this project doesn't use either feature
• Only usage is in examples/anthropic_comparison/native_approach.py (lines 59, 108) with basic messages.create() calls

Security: ✅ Includes bug fixes from upstream

Performance: ✅ No performance regressions expected

Recommendation: Safe to merge. The codebase uses only standard message creation APIs which remain unchanged.
