Adds pseudonymous, switchable social identities derived from the SAME root seed via an account index (NostrKeyDerivation.deriveFromSeed(seed, account)). HKDF is one-way so accounts are unlinkable to the Ğ1 key; account 0 is the original identity, byte-for-byte unchanged (no rotation for current users), and every account regenerates from the single seed — so switching adds nothing to back up. - SocialAccountStore: keystore-backed active account + max created. - Per-identity stores (chats, profile, name cache) namespaced by account scope (account 0 = legacy keys, no migration) so identities never mix. - switchSocialAccount() re-derives the identity, re-scopes the stores and restarts the inbox listener; RestartWidget rebuilds the tree to pick up the new social singletons. DB/inventory untouched. - Profile 'Your identities' switcher: list, create, switch (with a note that messages/contacts are kept separate per identity). i18n en/es/pt/ast. Tests: account-indexed derivation (legacy 0 unchanged, accounts distinct yet deterministic, negatives rejected); SocialAccountStore; per-identity store scope isolation. Resolves the flagged 'change identity' decision (open-decisions §B). Known: switching resets navigation to home (full tree rebuild).
