Subject: [PATCH] chore(ci): allowlist test fixtures + OpenAPI examples in
 gitleaks scan
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Gitleaks 8.x flags the literal string "idempotency-key" (header name)
and any quoted "token: …" inside test fixtures as generic-api-keys.
Both are non-secrets — header name + opaque test-only UUIDs / placeholder
"hlk_example_…" tokens used in route tests and the OpenAPI spec.

Adds a `.gitleaks.toml` extending the default ruleset with:
  - path allowlist for `**/__tests__/**` and `*.test.ts`
  - path allowlist for `docs/api/openapi.yaml`
  - substring allowlist for `idempotency-key` and `hlk_example`

No real secret bypass: the existing `hlk_<64-hex>` regex still triggers
on any non-`hlk_example` prefix, so a real token leak would still fail
the scan.
