AI Summary: Modify the C2PA Rust SDK to default the `AllActionsIncluded` field to `true` in claim generation, aligning with the updated specification. Consider adding a configurable setting to allow users to override this default behavior, potentially as part of a broader effort to manage default values for all actions within claims.

AI Summary: Investigate if reducing the build size of the C2PA Rust SDK is feasible and beneficial by selectively compiling features based on user needs. This involves analyzing the current codebase to identify features that can be conditionally compiled and assessing the trade-offs between build size and functionality.
