Add optional Shipgate scan for customer service tool-use cookbook

[pengfei-threemoonslab]

Problem

The customer service tool-use notebook demonstrates customer lookup, order lookup, and order cancellation, but there is no small release-readiness recipe for reviewing that tool surface without running the notebook.

Why static/local-first

This adds an optional scoped Agents Shipgate recipe with local Anthropic Messages API tool metadata, supplemental scope/owner inventory, and policy metadata. Agents Shipgate reads those local files only; it does not execute the notebook, call tools, make Anthropic API calls, run agents, or upload source.

Command run

PYTHONPATH=/Users/pengfeihu/code/shipgate/src python -m agents_shipgate scan -c tool_use/customer_service_shipgate/shipgate.yaml --ci-mode advisory --format json

For maintainers using the published package, the README shows:

pipx install agents-shipgate
agents-shipgate scan -c tool_use/customer_service_shipgate/shipgate.yaml --ci-mode advisory

Maintainer-safe note

This is docs/sample-metadata only. It does not add repo-wide CI and does not commit generated agents-shipgate-reports/ output.
