phab-try од Lars Eggert

Injects a Pushes panel on Phabricator D-pages and Bugzilla bug pages. The panel searches all tracked Mozilla repos (try, autoland, mozilla-central, beta, release, esr*) and shows every push that tested the revision or bug, each row tagged with its repo and decorated with status indicators:

• Landed revisions / fixed bugs get a plane-arrival icon
• Abandoned revisions and closed-without-fix bugs are struck through
• Backed-out pushes are struck through with a rewind icon

For each push the panel shows the timestamp, short hash (links to Treeherder), build / lint / tests badges, and a job-count summary. A non-fatal warning banner names any sources that returned errors so you know when results may be partial.

How it works

1. Multi-repo search. A background worker fans out across every tracked repo via the Treeherder API, filtering pushes by Differential Revision URL or canonical Bug N subject line.
2. mach try auto walk. For try pushes that carry no Diff Rev URL (submitted with mach try auto), the extension walks one level up the Mercurial commit graph via hg-edge.mozilla.org to find the parent patch commit.
3. Status decoration. D-revision status (Abandoned / Closed) is fetched from Phabricator; bug status from Bugzilla REST. Icons and badge colours are applied synchronously when the panel renders.
4. Backout detection. Each repo's recent push pool is mined for "Backed out..." commits; matching pushes are decorated automatically.
5. Auto-refresh. While any push has jobs still running, the panel polls for fresh data every two minutes and updates in place.

Also injects Phabricator / Bugzilla back-links into the Treeherder push-header bar for any try push URL.
