feat(symlog): Phase 2 — commit integration and symbol diff engine

- Wire _write_symlogs into muse commit after append_reflog; non-fatal - Add SymbolDiff dataclass and compute_symbol_diff with rename detection - extract_symbols: add file_path param (required by parse_symbols for correct keys) - _extract_body_hashes: body_hash-based rename matching (name-invariant) - compute_symbol_diff accepts optional rename key dicts for body-hash matching - 25 new tests (SL_13–SL_22): extract_symbols, compute_symbol_diff, created/ modified/deleted/renamed entries, initial commit, two-commit sequence, follow
