🤖 Bitwarden Claude Code Review

Overall Assessment: APPROVE

This tech-debt PR changes the accountSummaries field in LandingState, LoginState, VaultUnlockState, VaultState, and VaultItemListingState from List<AccountSummary> to ImmutableList<AccountSummary>, and updates UserState.toAccountSummaries() to return an ImmutableList. Producers and tests were updated consistently (persistentListOf, .toImmutableList()), and the pattern matches the existing ImmutableList usage already present in LandingState.environmentTypeOptions. The change is mechanical and low risk.

Code Review Details

• ♻️ : Redundant .toImmutableList() remains at four account-switcher call sites now that the state fields are already immutable (cleaned up only in LandingScreen)
