Note

Low Risk
Version/changelog updates only; no runtime code changes in this PR, so risk is limited to consumers picking up the new published versions (including @metamask/perps-controller major bump).

Overview
Bumps the monorepo release version to 953.0.0 and publishes @metamask/perps-controller as 5.0.0.

Updates the perps controller changelog with the 5.0.0 release notes (including documented breaking changes around HyperLiquid unified-account migration and mode-aware spot balance folding) and updates the compare links accordingly.
