Bumps idna from 3.13 to 3.18.

Changelog

Sourced from idna's changelog.

3.18 (2026-06-02)

  • When decoding a domain, add a display argument that will pass through invalid labels rather than raising an exception.

3.17 (2026-05-28)

  • Substantial 75% reduction in memory usage through new data structures and some optimization in processing speed.
  • Added a general 1024-character input length cap to the public validation, conversion, and codec entry points. This is well above any legitimate domain or label and guards against pathological inputs.

3.16 (2026-05-22)

  • Add a command-line interface (python -m idna, also available as the idna script). Encodes or decodes one or more domains supplied as arguments or on standard input, with options to select A-label or U-label output and control error handling.
  • Raise the minimum supported Python version to 3.9
  • Various code quality improvements

3.15 (2026-05-12)

  • Enforce DNS-length cap on individual labels early in check_label, short-circuiting contextual-rule processing for oversized input while staying compatible with UTS 46 usage.
  • Tidy core helpers: hoist bidi category sets to module-level frozensets (avoiding per-codepoint list construction), simplify length checks, and reuse the shared _unicode_dots_re from idna.core in the codec module.
  • Use raise ... from err for proper exception chaining and switch internal string formatting to f-strings.
  • Allow flit_core 4.x in the build backend.
  • Expand the ruff lint set (flake8-bugbear, flake8-simplify, pyupgrade, perflint) and apply the surfaced fixes; pin lint CI to Python 3.14.
  • Add Dependabot configuration for GitHub Actions.
  • Convert README and HISTORY from reStructuredText to Markdown.
  • Reference CVE-2026-45409 for the 3.14 advisory in place of the initial GHSA identifier.

Thanks to Felix Yan, Stan Ulbrych, and metsw24-max for contributions to this release.

3.14 (2026-05-10)

  • Removed opportunity to process long inputs into quadratic time by rejecting oversize inputs up-front. Closes a bypass

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
