Release v2.2.12

[2.2.12] - 2026-07-16

Fixed

• Live feed no longer pauses when one server is slow to respond - previously a single slow server could stall the entire polling cycle and freeze every server's feed on stale data; now each server polls independently and the others keep refreshing normally.
• Perf card no longer shows stale latency and cache numbers after a connection or timeout error from a server: the affected server's metrics are cleared to -- until the next successful poll, so the user can tell at a glance that the data is currently unavailable rather than outdated.
