thePR0M3TH3ANandClaude Fable 5 49682dd75c NIP-46 sign-in: remote-signer sessions behind the same facade, memory-only
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.
