// 1. Iterate all projects.
// 2. Compare the project's Image field against the parsed image's FullName().
// 3. For the matched project, iterate its stages and find one whose TagPattern
// matches the incoming tag using path.Match (glob semantics).
// 4. If multiple stages match, the first match wins (stages are ordered by name).
