feat(nip46): add skipSwitchRelays option to BunkerSignerParams

Adds a skipSwitchRelays option that prevents automatic switchRelays()
call in fromURI. This is useful when users want to call switchRelays
manually at their own pace, avoiding race conditions when making
immediate RPC calls after connection.

Fixes #526
