refactor: simplify NostrClient API for beginner-friendliness

Comprehensive rename of the NostrClient relay infrastructure to use
intuitive, self-documenting names instead of protocol-level jargon.

Interface/class renames:
- INostrClient → NostrClient (interface)
- NostrClient → DefaultNostrClient (implementation)
- IRequestListener → SubscriptionListener
- IRelayClientListener → RelayConnectionListener
- IOpenNostrRequest → SubscriptionHandle
- NostrClientStaticReq → StaticSubscription
- NostrClientDynamicReq → DynamicSubscription

Method renames:
- openReqSubscription() → subscribe()
- close(subId) → unsubscribe(subId)
- send() → publish()
- queryCount() → count()
- subscribe/unsubscribe(listener) → addConnectionListener/removeConnectionListener
- renewFilters() → syncFilters()

Callback renames:
- onEose → onCaughtUp
- isLive → isRealTime
- onStartReq → onSubscriptionStarted
- onCloseReq → onSubscriptionClosed

Extension function renames:
- query() → fetchAll()
- downloadFirstEvent() → fetchFirst()
- req() → subscribe()
- reqAsFlow() → subscribeAsFlow()
- reqUntilEoseAsFlow() → fetchAsFlow()
- sendAndWaitForResponse() → publishAndConfirm()
- queryCountSuspend() → count()
- queryCountMergedHll() → countMerged()
- reqBypassingRelayLimits() → fetchAllPages()
- updateFilter() → refresh() on SubscriptionHandle
