Migrates Controller construction in keychain to use the MultiChainAccount implementation from controller-rs (commit 1dd7ed8f6c7362fcc4b4c15c18d5a631008a0547). Key changes: - Replace CartridgeAccount with MultiChainAccount internally - Store metadata fields directly instead of using CartridgeAccountMeta - Update all instance methods to use async getAccount() helper - Migrate factory methods (create, login, apiLogin, fromStore) to use MultiChainAccount - Maintain backward compatibility with existing single-chain usage This sets up the foundation for multi-chain support while preserving all existing functionality and API compatibility. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>

Bug: Factory Methods Overwrite Authenticated Accounts
The login and other factory methods discard the authenticated CartridgeAccount obtained from initial login or creation calls. Instead, a new MultiChainAccount is created, which loses the established authentication state and session data, potentially leaving the controller in an unauthenticated state.

Note
Replaces CartridgeAccount/Meta with MultiChainAccount, stores metadata fields directly, adds async account accessor, and updates factory/instance methods to use JsChainConfig and provider-derived chainId.
