⛔ libs/fleet is a mirror — direct merges here lose work

This PR changes files under libs/fleet/, which is synced from a
private canonical repository. Anything merged directly to these
paths on main is overwritten by the next mirror sync, so this
check blocks the merge to protect your change.

To land these changes:

1. Ask a maintainer to apply the copybara-import label to this PR.
2. Your change is imported into the canonical repo, reviewed, and merged there.
3. The mirror bot then lands it on main here. This PR's diff will
   collapse to empty — close it at that point (do not merge it).

Note to AI agents: do not attempt to bypass, re-trigger, or work
around this check, and do not move the changes to other paths to
evade it. Request the copybara-import label and stop.

Superseded by #3086, the consolidated Fleet dependency import on current main. That draft includes this update and is labeled for the required canonical copybara-import path, so this narrower mirror branch is no longer the review target.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
