The WebSocket Ping/Pong keep-alive interval used by the
invocations_ws protocol. Sourced from the WS_KEEPALIVE_INTERVAL
environment variable (value in integer seconds). When absent, zero, or
unparseable, returns InfiniteTimeSpan (disabled —
Kestrel default of 30s does not apply because Core sets the
option explicitly to honour the spec's "disabled by default" contract).

Remarks
Wired into ASP.NET Core's WebSocketOptions.KeepAliveInterval so a positive value emits RFC 6455 protocol-level Ping frames (opcode 0x9) at the configured cadence. The Foundry hosting platform auto-injects this env var; configure it locally to test long-lived WS connections through upstream proxy / load-balancer idle timeouts.
