+Pagination and sorting for `profile timeline`
+
+Large profiling sessions no longer flood agent context with hundreds of commits:
+
+- **Default limit of 20**: `profile timeline` returns at most 20 entries unless `--limit N` is specified.
+- **`--offset N` flag**: Skip the first N commits for pagination.
+- **`--sort duration`**: Sort commits by render duration (slowest first) instead of chronological order.
+- **Paginated header**: Output shows `Commit timeline (showing 1–20 of 87):` when paginated, or `Commit timeline (87 commits):` when all results fit on one page.
