Redeploy the 25 MCP-enabled workers to ship the readOnlyHint/destructiveHint annotation fix

workers/_shared/kit/mcp.ts's toolDef() now sets annotations:{readOnlyHint:true,destructiveHint:false} (edited this session, confirmed exactly 2 internal call sites, no external consumers). This is a real, already-written, not-yet-deployed source change. Execute the actual Desktop Commander + wrangler deploy sequence for all 25 workers currently serving a live /mcp endpoint, and curl-verify the annotations field appears in a fresh tools/list response for at least 3 of them.
