Contributions summary:Thomas was involved in refactoring and renaming core search backend components. The primary focus of their work involved renaming `commit.CommitSearch` to `commit.CommitSearchJob`, `repos.ComputeExcludedRepos` to `repos.ComputeExcludedReposJob`, `run.RepoSearch` to `run.RepoSearchJob`, `searcher.Searcher` to `searcher.SearcherJob`, `searcher.SymbolSearcher` to `searcher.SymbolSearcherJob`, `structural.StructuralSearch` to `structural.StructuralSearchJob`, and `symbol.RepoUniverseSymbolSearch` to `symbol.RepoUniverseSymbolSearchJob` across multiple files within the repository. They also added trace tags to several job types and made improvements to formatting and logic within the search backend. This work appears to be focused on modernizing the search backend and improving tracing capabilities.
