Cover `--reference` from a local mirror (with & without `--dissociate`),
`--standalone-manifest` with a manifest file served over HTTP, and
`--manifest-depth`.
Teach the server to serve static files (`GitHost.publish_file`), let
`manifest_xml` take an absolute `fetch` URL, and add `move_aside` to
make git dirs disappear mid-test (deleting them fails on Windows).

Cover the go/repo-init flags used across Android (superproject, `-c`,
`--partial-clone`, `--partial-clone-exclude` & `--clone-filter`)
followed by the go/sync flags, under Git 2 & Git 3 defaults: projects
are pinned to the superproject, filtered blobs stay on the server,
excluded projects are full clones, and incremental syncs skip projects
whose pin didn't move. Also cover the default filter, and `sync -n`
then `sync -l` with a partial clone (where `-l` has to fetch blobs on
demand).
Add harness helpers to read a checkout's git config, list the repos a
client contacted, and create blobs that only exist in history.

Cover `repo sync -n` & `-l` on existing checkouts (interleaved &
phased), projects that were never fetched, and two-phase syncs with a
superproject. `-l` must not touch the network, which the tests check by
taking the server offline. Also cover tags (`--no-tags` & `sync-tags`),
`--prune`, `--force-sync`, `--force-remove-dirty` & `-d`.
Teach the harness to simulate outages (`GitHost.offline`) and to collect
the requests made during a block (`GitHost.watch_requests`), and add a
few `RepoClient` helpers.

Add tests/e2e/conftest.py with fixtures for writing end-to-end tests: a
session-wide git server, the published code under test, a per-test
namespace of server repos, and a repo client with an isolated HOME &
git config. Parametrize `git_defaults` to emulate Git 3 defaults
(reftable & `main` as the default branch) on older git.
Tests under tests/e2e/ are marked `e2e` and run after the unit tests in
`./run_tests`. Use `-m e2e` or `-m 'not e2e'` to select them. They're
skipped when `git http-backend` is unavailable, git is older than 2.28,
or not running from a git checkout.

Add `RepoClient`, which runs a standalone copy of the `repo` launcher as
a subprocess the same way end users do, and `publish_repo_source`, which
publishes the code under test (the current checkout, including
uncommitted changes) as a repo on the server so `repo init` installs it
into .repo/repo/ over HTTP.
Also add `GIT_DEFAULTS` so tests can emulate Git 3 defaults (reftable &
`main` as the default branch) on older git.

Add `GitHttpServer`, which serves the bare repositories under a
directory over smart HTTP by running `git http-backend` behind a small
threaded HTTP server on 127.0.0.1. Like Gerrit/GoB, it also serves
static `<repo>/clone.bundle` files. It records the requests it receives
so tests can check what clients fetched.
Add `GitHost`, which gives each test its own namespace of repos on a
shared server, with helpers to create & update a manifest repo.

This is the first piece of a hermetic end-to-end test harness for
running the real `repo` against a local git server.
Add tests/e2e/harness.py with `ServerRepo`, which creates bare
repositories, commits (including gitlinks for superprojects), branches,
tags & clone bundles without needing a worktree. Commits are written
with `git fast-import` using a fixed identity & a monotonic fake clock
so they're cheap & strictly ordered. Also add helpers to run git with
the user's git environment stripped & to write git config files
directly.
