✨ New Features

ShadowGuard variable name shadowing protection
Added a shadow protection mechanism that automatically detects and prevents variable name shadowing during code generation, improving the robustness of generated code.
Default behavior for unused parameters changed
Changed the handling of unused parameters from the default drop (discard) to error (report an error), helping developers catch potential parameter omissions earlier.

Fix missing quotes for generic type parameters in logs
Improved the generator's logging of Identity Target Type by properly wrapping type parameters with quotes, making log output more consistent and readable.
Fix identifier handling for cross‑package bare function calls
Fixed an issue where the extractor incorrectly recognised identifiers when handling cross‑package bare function calls.
Fix free variable shadowing of package aliases
Resolved a problem where free variable parameter names shadowed package aliases in non‑closure items. Adjusted the extraction logic to register package aliases earlier, ensuring that ShadowGuard correctly handles parameter lists and free variable mappings.
Fix shadowing caused by case‑sensitive variable names
Renamed the package‑level variable Db to db to avoid naming conflicts with the imported db package alias, and updated all code references accordingly.

Refactor ShadowGuard and free variable handling
Refactored the shadowing logic for free variables and improved the ShadowGuard mechanism, enhancing the overall robustness of the code generator.
Enhanced metadata in generated code
Added debug logs and clearer metadata information to the generated dig_gen.go files, making troubleshooting easier.

Update Redis DB Index configuration example
In the example module, added a new RedisDbIndex type and a default variable, updated the Ping method to receive and log the db index, and injected the db index via DI.
Update all generated dig_gen.go files
Synchronised the regenerated dig_gen.go files across all example modules.

Updated dependency versions and change logs
Removed the debug-aliases flag and lifted the "one function per module" restriction
Improved the third‑party library comparison matrix and cleaned up example code
