PR #7166 (refactor to isolate local object rename commit) extracted
rename_data_inner, rename_data_observed, and LocalRenamePreflightRejection
into disk/local/commit.rs. PR #7163 (drain control writes) was based on
code before the refactor and re-added the same definitions to local.rs,
causing 27 compilation errors (duplicate struct/method definitions and
unresolved helper symbols).
Remove the duplicate block (997 lines) from local.rs; the canonical
definitions in commit.rs are already imported via the module re-export.
Also fix 4 clippy warnings introduced by upstream:
- shared.rs: redundant guard pattern → direct pattern match
- tests.rs: needless struct update, needless borrow, cloned_ref_to_slice_refs
