Walkthrough

Documentation updates rename the public-facing output field from outputs.<checkName>.body to outputs.<checkName>.content in request chaining, and expand HTTP reference templating documentation to introduce namespaced canary.* and check.* variables alongside a new dependency output variables subsection.

Changes

Cohort / File(s)	Summary
Request Chaining Output Field canary-checker/docs/concepts/request-chaining.mdx	Renamed output field from outputs.<checkName>.body to outputs.<checkName>.content in examples and reference tables.
HTTP Reference Templating canary-checker/docs/reference/1-http.mdx	Expanded templating variable table to include namespaced canary.* (name, namespace, labels, id) and check.* (name, id, description, labels, endpoint) variables. Added "Dependency Output Variables" subsection documenting outputs.<checkName>.* fields (pass, message, duration, code, headers, content, json, elapsed, sslAge).
