1. Release Activity in Canary (#34374) …

   ## Overview
   
   This PR ships `<Activity />` to the `react@canary` release channel for
   final feedback and prepare for semver stable release.
   
   ## What this means
   
   Shipping `<Activity />` to canary means it has gone through extensive
   testing in production, we are confident in the stability of the feature,
   and we are preparing to release it in a future semver stable version.
   
   Libraries and frameworks following the [Canary
   Workflow](https://react.dev/blog/2023/05/03/react-canaries) should begin
   implementing and testing the feature.
   
   ## Why we follow the Canary Workflow
   
   To prepare for semver stable, libraries should test canary features like
   `<Activity>` with `react@canary` to confirm compatibility and prepare
   for the next semver release in a myriad of environments and
   configurations used throughout the React ecosystem. This provides
   libraries with ample time to catch any issues we missed before slamming
   them with problems in the wider semver release.
   
   Since these features have already gone through extensive production
   testing, and we are confident they are stable, frameworks following the
   [Canary Workflow](https://react.dev/blog/2023/05/03/react-canaries) can
   also begin adopting canary features like `<Activity />`.
   
   This adoption is similar to how different Browsers implement new
   proposed browser features before they are added to the standard. If a
   frameworks adopts a canary feature, they are committing to stability for
   their users by ensuring any API changes before a semver stable release
   are opaque and non-breaking to their users.
   
   Apps not using a framework are also free to adopt canary features like
   Activity as long as they follow the [Canary
   Workflow](https://react.dev/blog/2023/05/03/react-canaries), but we
   generally recommend waiting for a semver stable release unless you have
   the capacity to commit to following along with the canary changes and
   debugging library compatibility issues.
   
   Waiting for semver stable means you're able to benefit from libraries
   testing and confirming support, and use semver as signal for which
   version of a library you can use with support of the feature.
   
   ## Docs 
   
   Check out the ["React Labs: View Transitions, Activity, and
   more"](https://react.dev/blog/2025/04/23/react-labs-view-transitions-activity-and-more#activity)
   blog post, and [the new docs for
   `<Activity>`](https://react.dev/reference/react/Activity) for more info.
