v0.1.0-alpha.7

Changed — Quack is now a core DuckDB extension (v1.5.3+)

• DuckDB v1.5.3 (announced 2026-05-20) ships quack as a core
  extension. No more core_nightly repository and no more
  -unsigned / allow_unsigned_extensions requirement — INSTALL quack; LOAD quack; Just Works against any DuckDB v1.5.3+ session.
  README quickstart and the Python integration-test conftest.py
  are updated accordingly.
• Bumped the test extra to require duckdb >=1.5.3 (was
  >=1.5.2).
• Verified protocol compatibility: the full Python integration suite
  (26 tests) passes against DuckDB 1.5.3 with no driver-side
  changes.

CI — GitHub Release body now pulled from CHANGELOG

• The github-release job now checks out the repo, extracts the
  matching ## [VERSION] section from CHANGELOG.md (same awk
  pattern as gizmodata/gizmosql), and passes it to
  softprops/action-gh-release via body_path.
  generate_release_notes: true is kept as a fallback for tags
  whose CHANGELOG section is missing.
