Worker metrics: installed-package test against a published Server #394
Description
Follow-up from durable-workflow/.github#233. Worker metrics shipped in sdk-php 3.8.0, and the ready-age histogram in 3.10.0 (#306). The remaining evidence is a test that installs the published package and shows the metrics, including the histogram, against a published native Server.
Acceptance: a CI job installs the released sdk-php package, not the source tree, runs a worker against a published Server image, and asserts the metric names, labels and the ready-age histogram.

sdk-php owns this acceptance test. I am adding a small CI workflow and source-free smoke runner using the published SDK and an immutable native Server image. It will complete real workflow/activity tasks and assert poll/task metric names, bounded labels, paired durations and the ready-age histogram. Next: draft PR, run the exact published tuple in CI, then close with its result. No runtime release is needed for a test-only change.

Delivered by #403, merged as 53687e6. Published-package CI passes: https://github.com/durable-workflow/sdk-php/actions/runs/43399728706 . Tuple: SDK 3.17.0 (daa842c), native Server 3.8.0 (image index sha256:7988a23525d9e50e997a9f6f02e801300ed4f626de3cf6977033657ae7e9f58e), qualified bound PHP 8.3 profile. Real workflow/activity completion, all five worker instruments, exact bounded labels, paired durations, ready-age samples for each dispatch, empty query poll and managed-worker deregistration pass. The workflow retains the installed lockfile and observations for 14 days. No package release is necessary for this acceptance-only change; test containers and volumes were removed.
