fix(codama): Update authority seed to size_prefix to match bincode

[dhl]

This also brings in the enum_discriminator fix from codama 0.9.2

[Copilot]

Pull request overview

Updates Codama-derived IDL and generated clients to better match the stake program’s bincode serialization expectations (u64 length prefixes for strings and u32 enum discriminators), including the Codama 0.9.2 enum discriminator fix.

Changes:

• Bump codama / codama-macros to 0.9.2 and regenerate IDL artifacts.
• Ensure authority_seed strings are represented with a u64 size prefix in IDL and generated clients.
• Update JS generated enum encoding to use u32 discriminators and add schema tests validating these expectations.

Thanks! Looks good to me on the Codama side. Would just like @joncinque's approval on that one as well to make sure the binary layout is correct. 🙏

[joncinque]

Looks great, thanks!

[dhl]

Thanks so much, @lorisleiva and @joncinque.

Could we release an updated @solana-program/stake for npm to get the fix published?

[lorisleiva]

@joncinque The "Publish JS" workflow is currently broken for this repo. Is this because we're migrating to a Trusted Publisher setup on the shared actions?

[joncinque]

My apologies, I messed up the publish token turnaround, this should work on the next attempt

[lorisleiva]

Thank you! A new patch version of the JS package has been published.
