fix: drop relay.damus.io from default relay lists ahead of shutdown

relay.damus.io is being decommissioned, so remove it from every runtime
default/fallback relay set to stop the app and amy from wasting connection
slots on a dead host:

- commons Constants: remove `damus`; it dropped out of `bootstrapInbox`
  (default NIP-65 inbox) and `eventFinderRelays` (default outbox/fallback),
  both still carrying 6 healthy relays.
- ChessConfig: remove damus from CHESS_RELAYS / CHESS_RELAY_NAMES, leaving
  the 3 relays the FETCH_TIMEOUT comment already assumes.
- desktop DefaultRelays: remove damus and the also-dead relay.snort.social.
- desktop FollowPacks DISCOVERY_RELAYS: remove damus.
- amy NipCommand SEARCH_RELAYS: swap damus for the NIP-50-capable nostr.wine.

Comments, @Preview sample data, and test fixtures that mention damus.io are
left untouched — they have no runtime effect.
