Implements login-methods.md §LM5 phase one. Core gains nostr/nip46.ts -- a Nip46Client speaking kind-24133 RPC with NIP-44 transport encryption, bunker:// parsing, nostrconnect listen (secret echo is proof-of-scan), auth_url surfacing, and typed deadline errors -- plus subscribeLive on RelayConnection with re-REQ on reconnect, and live post-EOSE delivery in the MockRelay so tests exercise real round trips against a fake bunker. The ephemeral client key and Nip46Client live in the crypto worker (§LM5.4); nip46* actions bypass the serial queue so a signer waiting minutes for human approval cannot block other worker calls, and the signer's auth_url reaches the UI as the worker's first notification frame. The widget's connect screen runs both legs at once: a nostrconnect QR -- rendered as dot-style inline SVG with rounded finder eyes, per owner preference -- for phone signers, and a bunker:// paste box (password input; the URI carries a token). window.nostr is now an element-routed provider, so a NIP-46 session claims the slot and hosts reading it get the remote signer transparently; NIP-07 still leaves the slot to the extension. Sessions stay thin per §LM7: no vault, no persistence. Persistence remains gated on the external vault review (§LM5.3). 14 new tests (core fake-bunker e2e, QR geometry, signer delegation) and two policy pins: bunker option below the password path, element stays web-storage-free.
