Summary

Adds request-level authentication via BIP-340 Schnorr signatures using the NIP-98 HTTP Auth scheme (Authorization: Nostr <base64>)
Verified identities resolve to did:nostr:<pubkey> URIs that work with existing Solid ACL rules as acl:agent values — zero changes needed to the ACL layer
Existing auth behavior is unchanged — Nostr auth is only checked when no session is present

Changes

File	Change
`lib/api/authn/webid-nostr.mjs`	New — NIP-98 event verification with BIP-340 Schnorr signatures
`lib/api/authn/index.mjs`	Export nostr auth module
`lib/api/authn/webid-oidc.mjs`	Skip OIDC RS middleware for `Nostr` auth headers
`lib/handlers/allow.mjs`	Fall back to Nostr auth when no session userId
`package.json`	Add `@noble/curves`, `@noble/hashes` (audited, zero-dependency crypto by Paul Miller)
`test/unit/nostr-auth-test.mjs`	All 10 official http-schnorr-auth spec test vectors + 3 edge cases

How it works

A user with a did:nostr:<pubkey> in an ACL file authenticates by sending:

GET /resource
Authorization: Nostr <base64-encoded-signed-NIP-98-event>

ACL:

<#auth> a acl:Authorization;
  acl:agent <did:nostr:39a360...c85c2>;
  acl:accessTo </resource>;
  acl:mode acl:Read.

Specs

This is Phase 1 (middleware only). No login UI, sessions, or browser flows.

          feat: Add HTTP Schnorr signature authentication (Phase 1)

3d64b63

Add request-level authentication via BIP-340 Schnorr signatures
using the NIP-98 HTTP Auth scheme (Authorization: Nostr <base64>).

Verified identities resolve to did:nostr:<pubkey> URIs that work
with existing Solid ACL rules as acl:agent values — no changes
needed to the ACL layer.

Tested against all 10 official http-schnorr-auth spec test vectors
and verified live with read + write operations against a running
NSS instance.
