test(mwp7/phase2-mode-a): regression anchors LF_01+LF_02; adjacent corpus green (LF_03)

LF_01 — TestLF01RegressionAssertion (2 tests): test_LF_push_main_after_dev_sends_only_merge_commit: named permanent guard for muse#55; cites 1375→1 reduction; asserts commits_sent==1 with branch_have including sibling dev tip. test_LF_large_chain_sends_only_new_commits: 17-commit chain (mirrors #55 incident); asserts commits_sent==1, objects_sent==1.

LF_02 — TestLF02ObjectsSent (2 parametrized cases): pure_merge_zero_new_blobs: M re-uses D's snapshot → objects_sent==0 merge_with_one_new_blob: M adds one file → objects_sent==1 Guards against both over-sending AND over-excluding.

Helpers added: _merge_commit_pure(), _run_push_spy() (DRY wrapper). Spy updated to also capture objects_sent from walk['all_blob_ids'].

LF_03 adjacent corpus — zero regressions: test_push_branch_have.py 5 passed test_push_have_filter.py 27 passed test_push_step1_dag_walk.py 10 passed test_cmd_push_hardening.py 43 passed
