starknet-specs release v0.10.4

[github-actions]

A new version of starknet-specs has been released.

Release: v0.10.4
Tag: v0.10.4
Published: 2026-09-10T13:21:19Z
Current Katana spec version: 0.10.0

Release Notes

Scope: Wallet API
Adds STRK20 shadow account support, and an optional valid_until parameter to wallet_strk20Balances that lets a dapp request how long its authorization to read shielded balances stays valid.
The full node JSON-RPC, Proving API and P2P specs are unchanged in this release: nodes stay at 0.10.2, and the Proving API and P2P specs at 0.10.3.

This is the first stable release under the per-spec release scope described in the README: all files share one version, but each release changes only one spec, so implementations may correctly report different versions.
