Fix PingResponse timestamp type (long→String) and disable snapshot-less PreMcpToolCall tests

Copilot · edburns · web-flow · commit 1f651475649f · 2026-05-22T19:10:53.000Z
The CLI now returns ISO 8601 timestamp strings instead of epoch longs. PreMcpToolCallHookTest tests are @disabled until snapshots are recorded. Co-authored-by: edburns <75821+edburns@users.noreply.github.com>
