fix(delta): detect blob-identical file renames for files with no symbol tree

_detect_file_move_edits only matched renames via symbol tree body_hash overlap — files with no parseable symbols (plain .txt, unknown extensions) fell through to InsertOp + DeleteOp even when content_id was identical.

Strategy 2: after symbol-tree matching, compare raw blob content_ids for remaining unmatched added/removed paths. An exact match (score=1.0) is an unambiguous rename — emits PatchOp(from_address=old_path).

delta_summary now counts renamed files separately from modified files.
