- Added `registerMacroAlias()` public method to register aliases for existing macros
- Extracted shared registration logic into private `#registerMacroEntry()` helper
- Refactored `registerMacro()` to use `#registerMacroEntry()` for both primary macros and aliases
- Alias registration validates name format, prevents self-aliasing, and resolves alias chains to primary definition
- Aliases inherit handler and metadata from target but has source of the registration caller
