Major protobuf version upgrade may break yfinance compatibility

Medium Severity

The upgrade from protobuf 4.24.4 to 6.33.5 represents a 2-major-version jump that may introduce compatibility issues with yfinance==0.2.65, which depends on protobuf. The Snyk warning in the PR description indicates potential dependency concerns. This codebase heavily uses yfinance for market data fetching. If yfinance has an upper-bound version constraint on protobuf (e.g., <5.0), this change could cause dependency resolution failures or runtime errors. This compatibility should be verified before merging.
