File-size decomposition of the auth/key-handling manager (no behavior change).
- signerCapabilities.js: the signer capability/permission helpers
(resolveSignerCapabilities, hydrateExtensionSignerCapabilities,
attachNipMethodAliases, resolveActiveSigner, plus the permission-message
helpers). The three historically-public ones are re-exported from
SignerManager so js/nostr/client.js's imports are unchanged. Dropped the now
dead-in-SignerManager permission-message imports (they were already unused).
- signerRemoteHandshake.js: _waitForRemoteSignerHandshake lifted to an
instance-param function (only this.client / this.pendingHandshakeCancel /
this._decryptHandshakePayload became ctx.*; verified zero leftover `this`),
with a thin delegator on the manager.
SignerManager.js: 1516 -> 1145 lines (back under its 1156 limit).
Build + full unit suite green, incl. the NIP-46 handshake tests
(nip46-wait-handshake, nip46-prepare-handshake, nip46-silent-restore,
nostr-login-permissions) that exercise this path.
