Add git-first push ingestion with Mercurial fallback for repositories transitioning from hg to git. This enables a gradual migration where repos can be configured with a git_url to try GitHub first. Model changes: - Add git_url and git_branch fields to Repository model - Add RevisionMapping model for hg<->git SHA mapping New modules: - git_pushlog.py: GitPushlogProcess and fetch_git_push() for fetching push data from GitHub API - revision_mapper.py: RevisionMapper class for mapping between hg and git revision SHAs via DB cache, GitHub search, cinnabar mapfiles, or local git log parsing Modified ingestion paths: - PushLoader._try_git_first(): intercepts hg pushes and tries Git when git_url is configured on the repo - pushlog_tasks: fetch_push_logs dispatches to git or hg polling; new fetch_git_push_log task with hg fallback - ingest command: ingest_push() tries git-first for transitioning repos Backfill command: - backfill_git_pushes management command re-maps Push/Commit revisions from hg SHAs to git SHAs, with dry-run, chunking, rate limiting, resume support, and --flip-dvcs-type to complete the migration Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Backend: - _ingest_git_first() now accepts both git SHAs and hg revisions, checking if the revision exists in git before falling back to hg-to-git mapping - validate_revision() in job_loader checks RevisionMapping when a push isn't found, rewriting the origin revision to the git SHA so tasks referencing hg revisions link to git pushes - PushSerializer exposes is_git_revision (computed from RevisionMapping join, no new migration needed) Frontend: - RepositoryModel stores gitRevisionHrefPrefix/gitPushLogUrl when git_url is set, alongside the existing hg defaults - getRevisionHref(), getPushLogHref(), getRevisionBaseUrl() accept isGitRevision param to select the correct URL per push - Push, RevisionList, Revision, RevisionLinkify, CommitHistory all thread is_git_revision from the push API response through to links Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Add git-first push ingestion with Mercurial fallback for repositories
transitioning from hg to git. This enables a gradual migration where
repos can be configured with a git_url to try GitHub first.
Model changes:
New modules:
push data from GitHub API
git revision SHAs via DB cache, GitHub search, cinnabar mapfiles,
or local git log parsing
Modified ingestion paths:
when git_url is configured on the repo
new fetch_git_push_log task with hg fallback
Backfill command:
from hg SHAs to git SHAs, with dry-run, chunking, rate limiting,
resume support, and --flip-dvcs-type to complete the migration
