Phase 3 of multi-repository task support: comments now carry an
optional repositoryId so two repos with the same file path render
their own comment threads instead of bleeding together.
- CommentBase.repositoryId (optional, backwards compatible).
- getCommentsForFile gains an optional repositoryId arg; legacy
comments without a repositoryId match any repo filter so persisted
data keeps showing.
- Diff store interface in lib/diff/types.ts mirrors the new arg.
- Tests cover per-repo filter, omitted-arg fallback, and legacy data.
