Adds a 'serverless' workspace mode that points the desktop app at any generic public Nostr relay (e.g. wss://relay.damus.io) with zero Sprout server infrastructure — no Postgres, no HTTP /query|/events bridge, no NIP-98 auth. Reuses Sprout's native event kinds (39000 channel metadata, 39002 membership, kind 9 messages, h-tag scoping); 'serverless' is purely a transport + auth concern, so the server-mode path is untouched. Transport: reads/writes go over plain WebSocket (REQ/EOSE, EVENT/OK) instead of the HTTP bridge; NIP-42 AUTH is answered only if the relay challenges. Desktop backend: - AppState.serverless flag + is_serverless(); apply_workspace gains a flag - ws_relay.rs: query_relay_ws / submit_event_ws / publish_signed_event_ws - relay.rs: query_relay/submit_event + agent profile sync branch to WS - events.rs: build_channel_metadata_serverless (39000) + members (39002) - create_channel/open_dm publish those events directly (DM ids = UUIDv5 over sorted participants so both sides converge without a server) - managed agents inherit SPROUT_SERVERLESS into the ACP subprocess env Agents (full support, not a follow-up): - sprout-acp: RestClient + HarnessRelay gain serverless mode; query/submit use plain WS, NIP-42 handshake skipped on (re)connect; SPROUT_SERVERLESS env/arg - sprout-cli: SproutClient serverless WS query/submit; --serverless flag, to_ws_url helper, NetworkMsg error variant - npub respond-to permissions are in-process and work unchanged Frontend: - Workspace.mode + workspaceMode()/isServerlessWorkspace() helpers - relayClient.setServerless() skips the AUTH-wait on connect; late challenges still answered so writes succeed on relays that require auth - ServerlessContext/useIsServerless() hides search, pulse, projects, workflows - Serverless toggle in the Add Workspace dialog and Welcome screen Docs: docs/SPROUT_LITE_MODE.md updated with the implementation + testing steps.
