The `changes` vec was capped at 15 entries, so `changes.len() - 10` could only reach 5 — reporting "+5 more" when 190 lines were actually truncated. Fix: track `added + removed` directly and compute true overflow as `(added + removed) - 10`. Adds 7 accuracy tests across 4 modules to lock in correct overflow reporting: - diff_cmd: overflow count matches true total (200 changes → "+190 more") - diff_cmd: no spurious overflow message for 8 changes - git: format_status overflow count is exact (25 staged → "+10 more") - git: compact_diff recovery hint present when hunk is truncated - grep: documents uncapped-vector invariant that prevents the diff bug - filter: smart_truncate kept + reported_more == total_lines Closes the test gap flagged in testing-patterns.md backlog for diff_cmd.rs.

(truncated)" with no count. An LLM had no way to know if 5 or 450 lines were dropped. Replace with "... (N lines truncated)" by tracking hunk_skipped separately from hunk_shown — flush the count at each hunk/file boundary. 2. filter_log_output: commit body beyond 3 lines was silently dropped. A 20-line body explaining a breaking change would show 3 lines with no indicator that 17 were omitted. Now appends "[+N lines omitted]" when body_omitted > 0. Adds 2 RED-then-GREEN tests to lock in the new behavior.
