feat: batch-streaming fetch + fix push author override

wire_fetch_stream: replace load-all-then-stream with per-batch streaming. For each _COMMIT_BATCH=50 commits: load those snapshots, emit O frames for new objects, emit C frame. Peak memory is O(batch) not O(full_repo), matching git's incremental pack protocol. Fixes OOM crash on large repos.

Also remove 'author: wire_commit.author or pusher_username' fallback — that fallback overwrote the author baked into the commit's content hash, breaking hash verification on clone for any commit with author:''.

TDD: 7 new tests in test_wire_batch_stream.py (B1–B7).
