SFSafeSymbols

Replaces error-prone string literals like `UIImage(systemName: "circle.fill")` with compile-time checked types such as `UIImage(systemSymbol: .cCircleFill)`, preventing runtime crashes from typos.

Symbols are annotated with @availability flags based on Apple's SF Symbols versions, ensuring they're only accessible on supported OS versions, as detailed in the Supported Versions table.

Each symbol includes documentation for layersets, localizations, and appearances directly in code, eliminating the need to look up details in the SF Symbols app.

Provides both implicit automatic localization and explicit static/dynamic methods, with compile-time checks for available localizations, as shown in the Localization section.
