Adds a small Django project in example/ so users can see LookupWidget working before they wire it into their own app. It's a comics catalogue: one form edits an issue's series, language and characters.

What it shows

• SeriesLookup on a ForeignKey, with rank_fields, a custom label, select_related and max_results = 10. Searching "man" demonstrates both ranking and the cut-off message.
• CharacterLookup on a ManyToManyField with multiple=True, searching name and alias.
• LanguageLookup, a plain Lookup over a list, on a CharField with choices. The model field's choices still validate the submitted value.
• IZAYA_CLASSES and a small stylesheet that put the selected values inside the search box. The form page also logs izaya:select and izaya:remove events.

Running it

uv sync
uv run example/manage.py migrate      # also loads sample data
uv run example/manage.py runserver

The page loads htmx 2.0.11 from jsdelivr, so it needs a network connection.

Other changes

• pyproject.toml: per-file ruff ignores for example/, like the existing ones for tests/*.
• .gitignore: ignores example/db.sqlite3.
• README.md links to the example, and CHANGELOG.md has an entry under Unreleased.

The example isn't packaged, because the build only includes izaya/. CI doesn't run it either.
