[blacksmith-sh]

This PR has been automatically generated by a team member in your GitHub organization using Blacksmith's Migration Wizard. This PR changes the following:

1. Your selected workflows will now run on Blacksmith's 2x faster hardware (e.g., runs-on: blacksmith-4vcpu-ubuntu-2204). Learn more about the different instances available to choose from.
2. Your jobs running on Blacksmith will now have all official GitHub and popular third-party cache actions automatically interact with our 4x faster, colocated cache. Learn more about Blacksmith's actions cache.
3. Your GitHub Actions will now actually be observable. Learn more about Blacksmith's logging and other observability features.

Greptile Summary

This PR migrates all GitHub Actions workflows from GitHub-hosted runners (ubuntu-latest, ubuntu-22.04, macos-latest, windows-latest) to Blacksmith-hosted equivalents, and swaps docker/setup-buildx-action@v3 for useblacksmith/setup-docker-builder@v1 in the Docker publish workflow. The migration is consistent across all 28 files with one exception: the self-host-daemon-e2e matrix in tests.yml updated its Ubuntu entry but left macos-latest unchanged while every other macOS runner in the PR was migrated to blacksmith-6vcpu-macos-15.

Confidence Score: 4/5

Safe to merge; one macOS runner in a matrix was missed but still runs correctly on GitHub-hosted hardware.

All changes are runner label swaps with no logic modifications. The only finding is a P2 inconsistency where macos-latest was not migrated in one matrix entry, which doesn't block functionality.

tests.yml — self-host-daemon-e2e matrix still references macos-latest.

Important Files Changed

Filename	Overview
.github/workflows/tests.yml	Migrated all runner labels to Blacksmith equivalents, except macos-latest in the self-host-daemon-e2e matrix which was missed.
.github/workflows/publish-docker.yml	Replaced docker/setup-buildx-action@v3 with useblacksmith/setup-docker-builder@v1 and migrated runner label to Blacksmith; QEMU step retained correctly for multi-platform builds.
.github/workflows/build-tauri.yml	Migrated linux runner labels to Blacksmith; Windows and macOS Tauri build targets left untouched (correct).
.github/workflows/release.yml	All ubuntu-latest runners migrated to blacksmith-4vcpu-ubuntu-2404; no logic changes.
.github/workflows/extended-db-tests.yml	Both ubuntu-22.04 and ubuntu-latest jobs correctly migrated to matching Blacksmith equivalents.
.github/workflows/build-ui-mobile-local.yml	All runner labels migrated; macos-26 correctly mapped to blacksmith-6vcpu-macos-26.

Incomplete macOS migration in matrix

The macos-latest entry in this matrix was not migrated to blacksmith-6vcpu-macos-15, unlike every other macos-latest occurrence in this PR (e.g. installers-smoke-macos, self-host-launchd-e2e, mobile-e2e-ios). This self-host-daemon-e2e job will still run on GitHub-hosted macOS runners rather than Blacksmith.
