Patch Changes

f77355c: fix(mcp-common): allow workflow eventType and treat wallTimeMs/cpuTimeMs as optional in observability response schema

The Workers Observability response schema (zCloudflareMiniEvent / zCloudflareEvent in packages/mcp-common/src/types/workers-logs.types.ts) was missing 'workflow' from the eventType enum, and zCloudflareEvent re-declared cpuTimeMs / wallTimeMs as required. Cloudflare Workflow events emit eventType: "workflow" and do not always include the time fields, so the workers-observability MCP's query_worker_observability tool would reject any response containing a workflow event with a Zod validation error and return no data to the caller.

This left the MCP unable to surface logs from any Worker built on Cloudflare Workflows. Adding 'workflow' to the enum and making the time fields optional unblocks those queries.
