Phase 1.1 of multi-repository task support: extends the lifecycle types
with explicit per-repo lists, while keeping the legacy single-repo
top-level fields as the synthesized fallback. No caller behavior changes
yet — preparers still see length-1 specs for single-repo launches.
- LaunchRequest.Repositories []RepoLaunchSpec + RepoSpecs() helper.
- EnvPrepareRequest.Repositories []RepoPrepareSpec + RepoSpecs() helper.
- EnvPrepareResult.Worktrees []RepoWorktreeResult for per-repo outcomes.
- runEnvironmentPreparer forwards req.Repositories into the prepare
request, inheriting the request-level RepoSetupScript when each
per-repo entry has none.
- Tests cover explicit-list precedence, synthesized fallback, and
repo-less requests.
