Note

Medium Risk
Ships behavioral account-creation changes (v1 createAccount removal) and eth-snap-keyring major alignment via dependency bumps, though this PR only changes versions and lockfiles.

Overview
Monorepo release 1115.0.0 that cuts and wires new versions of @metamask/accounts-controller (39.0.5) and @metamask/multichain-account-service (12.1.0), then bumps those dependencies (and changelogs / yarn.lock) across the affected workspace packages.

multichain-account-service@12.1.0 (documented for this release) drops the legacy v1 createAccount path for BIP-44 Snaps in favor of createAccounts, to avoid side effects such as auto-selecting a non-EVM account after creation that conflict with the group model.

accounts-controller@39.0.5 is a patch release that realigns declared dependencies—notably @metamask/eth-snap-keyring ^23.0.0—so client dependency trees pick up the intended major version alongside related keyring/messenger bumps already noted in that package’s changelog.

No runtime source changes appear in this diff; it is version, changelog, package.json, and lockfile updates to publish the above.

Should this be a breaking change ?
