feat: enhance dependencyKeys handling to include function arguments

[PellegrinoDurante]

This pull request updates how the dependencyKeys property works in the cache plugin, ensuring that both the result of the cached function and its arguments (fnArgs) are passed to the dependencyKeys function. This makes cache invalidation more flexible and accurate. The changes also add a corresponding test to verify this new behavior.

Improvements to cache plugin API:

• Updated the logic in remapDependencyKeys and its usage so that the dependencyKeys function now receives both the result and the function arguments (fnArgs) as parameters, allowing for more context-aware cache key generation. (src/plugin.ts, [1] [2]
• Clarified documentation in README.md to specify that dependencyKeys receives the result as the first argument and function arguments as the second argument.

Test coverage:

• Added a new test to ensure that the dependencyKeys function receives the correct arguments (result and fnArgs), and that cache keys are registered appropriately. (src/index.test.ts, src/index.test.tsR155-R186)

• Added fnArgs parameter to the remapDependencyKeys function
• Updated dependency key function calls to pass both result and function arguments
• Added comprehensive test coverage for the new functionality
• Updated documentation to reflect the new function signature
