feat: minify DOM 도구 추가 및 기존 CLI 도구 성능 최적화

[seonghobae]

불필요한 공백을 제거해 JSON 크기를 줄이는 minify_dom.py 도구를 추가하고, 테스트 커버리지를 100% 달성했습니다. 기존 도구들의 json.loads에 read_bytes()를 적용하여 성능을 최적화했습니다.

Pull request overview

This PR adds a new CLI utility to minify parsed NewsDOM JSON outputs (reducing file size by removing unnecessary whitespace) and updates existing CLI tools to load JSON via Path.read_bytes() for minor performance/memory improvements.

Changes:

• Added tools/minify_dom.py CLI (plus tests) to write minified NewsDOM JSON.
• Updated multiple existing tools/*.py scripts to use json.loads(path.read_bytes()) instead of read_text(...).
• Documented the new tool and the bulk optimization in CHANGELOG.md.

• json.dump(..., separators=(",", ":")) still leaves ensure_ascii=True (default), which will escape non-ASCII characters (e.g., Korean/Japanese) into \uXXXX sequences and can increase output size. If the goal is file-size minimization, set ensure_ascii=False so UTF-8 is emitted directly.

    with out_path.open("w", encoding="utf-8") as f:
        json.dump(data, f, separators=(",", ":"))

tools/minify_dom.py:24

• json.dump(...) defaults to ensure_ascii=True, which will escape non-ASCII characters (e.g., Korean/Japanese) into \uXXXX sequences and can increase file size, undermining the goal of “minify”. Other tools in this repo consistently use ensure_ascii=False when writing NewsDOM JSON.

tools/minify_dom.py:24

• This CLI writes JSON with the default ensure_ascii=True, which escapes non-ASCII characters. Other tools in this repo write NewsDOM JSON with ensure_ascii=False to keep UTF-8 output (e.g., tools/merge_dom.py and tools/split_dom.py).

    with out_path.open("w", encoding="utf-8") as f:
        json.dump(data, f, separators=(",", ":"))

pyproject.toml:22

• pymdown-extensions is a docs/Markdown toolchain dependency, but it has been added to the runtime [project] dependencies even though it is not imported anywhere in src/ or tools/. This increases the default install footprint; it should live under the docs extra (and then regenerate uv.lock accordingly) unless the runtime truly needs it.
