v4.1.0

[4.1.0] - 2026-07-16

Changed

• Move remote debugging support to the optional debug extra. Install
  iris-pex-embedded-python[debug] before enabling debugpy integration.
• Standardize contributor verification through the dev extra and tox.
• Publish packages only from explicit releases after verification.
• Update the default PersistentMessage schema mode from extend to managed
  for compatibility with iris-persistence 0.3.

Fixed

• Make CLI mocks resolve consistently on Python 3.10 when iop.cli.main is
  also exposed as the public CLI function.
• Preserve pytest's real exit status when preview IRIS changes the process
  status during Embedded Python interpreter shutdown.

Internal

• Add wheel-content and installed-ObjectScript validation.
• Refactor persistent-message resolution and production/migration internals
  without changing their public interfaces.
