Before

--summary always listed the five most frequent error messages, so on a log with many distinct failures the rest were hidden, and on a short log five lines were more than needed.

After

--top N (or --top=N) sets the number of listed error messages, from 1 to 100. Without it nothing changes.

$ logslice errors.log --summary --top 2
Level counts:
DEBUG: 0
INFO: 0
WARNING: 0
ERROR: 3
CRITICAL: 1
Top 2 error messages:
  2  Disk full
  1  Timeout
Skipped lines: 0

It works with both --summary-format text and json. An invalid value exits with status 2 and an argparse message; --top without --summary exits with status 2 and logslice: --top requires --summary.

How

• src/logslice/filters.py: parse_top accepts one to three ASCII digits from 1 through 100.
• src/logslice/summary.py: render and render_json take top (default 5).
• src/logslice/cli.py: the --top option and the check that it needs --summary.
• README.md: options row and a Top N example.
• Tests: new tests/test_top.py, plus small additions to tests/test_cli.py and tests/test_summary.py.
