Smithy Release - December 30, 2025

[nateprewitt]

This is a set of changes to release the 0.3.0 versions of smithy-core and smithy-aws-core, along with their dependencies. This will also bring the code generator up to date so that the next set of clients we release will pull in the minor version updates.

Changes for smithy-aws-event-stream, smithy-http, and smithy-json are being done as patch versions which can be picked up immediately as they're bugfixes or minor stylistic enhancements.
