Telemetry for skipped thumbnails

Skipped artifact thumbnails get logged and warned about, but only under a flag that's off.

Thumbnail skip telemetry and publish warnings exist but fire only behind a thumbnail flag that is off by default.

What

A failed or skipped thumbnail read during artifact publish is recorded as an event, and the reason is passed back to the caller as a publish warning. It fires only when the thumbnail feature flag is on, which it is not by default in this build.

Evidence

g("artifact_publish", "thumbnail_skipped")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
