Switching from a NIP-46 account to another account (e.g. an nsec account) failed to
switch BACK with "No remote signer session is stored on this device." Root cause:
disconnectRemoteSigner() defaults to keepStored:false and calls the no-argument
clearStoredNip46Session(), which removed the entire per-account v2 map
(bitvid:nip46:sessions:v2) — deleting EVERY saved account's session, not just a
teardown of the live connection. Four nip46Connector connect/handshake-error paths
call the same no-arg clear, so any connect hiccup also nuked all sessions.
Fix: the no-argument clearStoredNip46Session() now clears ONLY the legacy v1
"last-connected" default slot and leaves the per-account v2 map intact. A specific
account is still forgotten via clearStoredNip46Session(pubkey) (unchanged), so
removing one account is unaffected while switching between saved NIP-46 accounts
survives connection teardown.
Spec correction: the prior test asserted the buggy "no-arg clear wipes everything";
replaced with the corrected behavior + a switch-away/switch-back regression.
Test: tests/nip46-multi-account.test.mjs (7). Lint + build green.
NOTE: this prevents future wipes; a session already deleted by the bug must be
reconnected once (Login → remote signer) — after which switching persists.

Mirror the per-account nsec key store for remote-signer sessions: move from a
single slot (bitvid:nip46:session:v1) to a per-user-pubkey map
(bitvid:nip46:sessions:v2) so several saved NIP-46 accounts each keep their own
reconnectable session and the profile switcher can move between them.
Previously only the last-connected session survived, so switching among saved
NIP-46 accounts reconnected the wrong one (or failed).
- nip46Client.js: new per-pubkey session map keyed by userPubkey.
readStoredNip46Session takes an optional target pubkey; writeStoredNip46-
SessionSync writes both the map and the v1 last-connected default;
clearStoredNip46Session(pubkey) forgets one account (no-arg wipes all). Legacy
v1 slot migrated into the map on first read. Adds listStoredNip46SessionPubkeys().
- SignerManager: useStoredRemoteSigner({ pubkey }) selects the target account's
session and, on access-denial, forgets only that account. getStoredNip46-
Metadata(pubkey) is per-account.
- nip46 provider threads expectPubkey into the reuse call so a switch reconnects
the requested account, with the expectPubkey guard as a backstop.
nip46Connector.js is dead code; the live path is entirely in SignerManager.
Tests: tests/nip46-multi-account.test.mjs (7).
