Context

Final release task for milestone 0.3.9. Tracked separately so it shows
up in the milestone burndown and so the actual release steps have a
single owner / acceptance gate.

Blocked by: all other 0.3.9 milestone issues being closed (especially
#198 / PR 2 with the 13 High-bug fixes).

Scope

1. pyproject.toml:7 — bump version = \"0.3.8\" → \"0.3.9\".
2. CHANGELOG.md — add new top section ## 0.3.9 with:
   • BREAKING CHANGES: subsection listing all new Click required
     flags / per-type validation guards from PR 2 (issue 0.3.9 — Системный аудит мутирующих CLI-команд: 13 High багов, нужен автогейт WSDL↔CLI #198 H1–H13).
     Mirror style of the existing ## 0.3.8 section.
   • WSDL parity gate subsection — describes PR test(wsdl): system parity gate for mutating CLI commands (#198) #205 and its
     deliverables (tests/test_wsdl_parity_gate.py, new
     get_required_fields() / get_required_item_fields() helpers in
     direct_cli/wsdl_coverage.py).
   • Refs line citing all closed issues in milestone 0.3.9.
3. Verify: pip install -e . && direct --version → direct, version 0.3.9.
4. bash scripts/release_pypi.sh all — publishes to both TestPyPI and
   PyPI (PEP 517 build, see memory feedback_release_process.md).
5. Create signed tag v0.3.9 from main, push to origin.
6. Close milestone 0.3.9 on GitHub.
7. Smoke-test pip install direct-cli==0.3.9 from a clean venv.

Acceptance criteria

• pip show direct-cli | grep Version returns 0.3.9 after install
  from PyPI.
• git tag --list 'v0.3.9' lists the new tag.
• CHANGELOG.md top entry is ## 0.3.9.
• All other 0.3.9 milestone issues are CLOSED before publishing
  (release blockers).
• PyPI release page shows the new artifact.

Out of scope

• Migration guide for breaking changes (covered in CHANGELOG itself).
• Backporting bugfixes to 0.3.x maintenance branch (none exists).
