fix(deps): update proxy-addr, shell-quote and wrangler to patched versions (#971)

npm audit fix in the root and in packages/mcp-server. proxy-addr 2.0.8 fixes
the IP spoofing through IPv4-mapped IPv6 trust subnets (GHSA-jqcg-44mw-7w3h),
shell-quote 1.12.0 fixes the command injection through a line terminator, and
wrangler 4.149.0 brings a miniflare that no longer bundles the vulnerable
sharp 0.35.4. No package is added; 56 lock entries for miniflare's sharp
binaries go away.
