PRIK 0.2.0

Added

• Added maintained FFTPACK and MINPACK examples built from the upstream
  fortran-lang projects. Their build scripts, user guides, and numerical tests
  cover all 31 FFTPACK and 22 MINPACK public procedures.
• Added Python-owned, read-only NumPy snapshots for supported public Fortran
  parameter arrays, including MINPACK's dpmpar constants.
• Added declaration-expression support for richer arithmetic, comparisons,
  conditionals, array inquiries, and local, imported, or standalone
  specification functions, including native-dependent result extents.
• Added exact NumPy Boolean-array conversion for compiler-measured 8-, 16-,
  32-, and 64-bit Fortran logical kinds, with canonical writeback.
• Added WrapperBuildResult.import_module() to load a generated extension
  explicitly without changing sys.path.

Changed

• Moved documentation and maintainer-tool tests to tests/docs/ and
  tests/tools/, removed the generic tests/shared/ bucket, and mirrored
  internal tests by production package with narrower support helpers; removed
  recursive layout-policing tests that froze maintainer organization, retaining
  exceptional release safety under tests/workflows/. The maintainer-tool and
  workflow-safety suites, blocking static analysis, and focused documentation
  smoke checks now also run through the repository's tracked pre-push hook,
  together with one compiled scalar-wrapper smoke test, for earlier local
  feedback while remaining enforced by GitHub Actions.
• Simplified the documented DGESV validation and the LAPACK test suite to use
  explicit NumPy Fortran-order copies, with documented numerical-test helper
  conventions.
• Aligned the documented MINPACK hybrd1 callback example with its runnable
  test, made it verify callback invocation, and made its test problems
  self-contained; FFTPACK workspace initializer tests now validate a paired
  transform against NumPy or SciPy.
• Renamed the developer-facing wrapper generation package from
  prik.wrapper_codegen to prik.codegen; the old import path was removed.
• Expanded public interface resolution so implemented unnamed interfaces and
  public generics can be wrapped without exposing private implementation
  procedures.
• Expanded the Real Libraries CI lane to build and test BLAS, LAPACK, FFTPACK,
  and MINPACK, with cached native BLAS and LAPACK builds where available.
• Made performance comparisons faster and less order-sensitive with balanced
  A/B/B/A runtime measurements, merged samples, smaller worker budgets, and
  four measured clean builds after warm-up.
• Refreshed the README and website around the canonical
  PRIK — Python Runtime Interop Kit identity, with a concise FAQ, a fair
  PRIK-versus-f2py guide, clearer array guidance, and searchable real-library
  examples, including a four-library capability and validation summary, a
  concise statement of current limitations, and a derived-type inheritance
  walkthrough.
• Hardened preprocessing, compiler-derived type probes, semantic policy
  completion, and multi-source build reporting so unsupported contracts fail
  earlier with clearer diagnostics.

Fixed

• Preserved authoritative public interface signatures when linked legacy
  implementations use different internal storage declarations, including
  FFTPACK's zfftf complex-array interface.
• Corrected SciPy reference inputs for the LAPACK dstemr and dstebz tests
  and strengthened BLAS and LAPACK routine validation with independent
  mathematical expectations.
