Claude 18c576a068 fix(relay-server): acknowledge a superseded replaceable with OK true duplicate:
Second finding from the Marmot headless harness on geode. wn's `keys
publish` mints a KeyPackage (kind 30443, same `d` tag) in the same second
as the one its bootstrap already published; NIP-01's lowest-id-wins tie
keeps the stored one, and the insert of the loser trips the addressable
unique index. The store classified that as a rejection carrying SQLite's
text — "UNIQUE constraint failed: event_headers.kind, event_headers.pubkey,
event_headers.d_tag" — so the relay answered OK false with a reason no
client can classify, and MDK filed it as "publish acknowledgement
unknown" and retried forever.

nostr-rs-relay, which this harness was validated against, does not even
attempt the insert when a newer version exists and acknowledges the event
as `OK true "duplicate: ..."` (its Duplicate status maps to true). Match
that: the replaceable and addressable unique-index failures now classify
as RejectionReason.SUPERSEDED, a `duplicate:`-prefixed reason the session
already answers with OK true. The stored version is untouched, nothing is
fanned out, and the STORE-W01/W02 contract in the event-store-semantics
skill is updated to say so.

Tests: NostrServerTest covers an older kind-0 re-insert and the
same-second kind-30443 tie, asserting the OK true duplicate: reply and
that the winner remains the only stored version.
