Export version attributes from main package

[mashhoorahdal]

Description

This PR fixes issue #207 by exporting version attributes from the stixpy.net.attrs module.

Changes Made

• stixpy/net/attrs.py: Added all version attributes (Version, VersionU, MinVersion, MinVersionU, MaxVersion, MaxVersionU) to the module's __all__ list
• changelog/209.bugfix.rst: Added changelog fragment documenting the bug fix
• stixpy/net/tests/test_client.py: Added comprehensive tests to verify version attributes can be imported and function correctly

Testing

• Added unit tests that verify all version attributes are accessible via import
• Tests confirm version matching functionality works for all attribute types
• Tests verify support for uncompleted versions (V02U format)

Issue Reference

Fixes #207: Version attrs not exported in all

Checklist

• Tests pass
• Changelog fragment added

So that issue was referring to the Fido attrs in the file indicated below, not the package version.

Fixed the PR @samaloney

[mashhoorahdal]

Added missing version attributes in __all__

[samaloney]

Great thanks this looks good.

One of the main reasons is the the __all__ control what function etc are included in the generated documentation and now these are e.g. https://stixpy--209.org.readthedocs.build/en/209/reference/net.html#module-stixpy.net.attrs

Once the tests pass will get this merged

Make MaxVersion attributes inclusive

Summary

MaxVersion and MaxVersionU were previously implemented as exclusive upper bounds using a strict < comparison.
This caused MaxVersion(n) to reject version Vnn, which is unintuitive and inconsistent with how version constraints are typically interpreted.

With the availability of newer STIX data versions (e.g. V03), this off-by-one behavior became visible and resulted in incorrect attribute matching.

---

What changed

• Updated MaxVersion and MaxVersionU to use inclusive comparison (<=)
• Ensures:
  • MaxVersion(3) matches V03
  • MaxVersion(3) does not match V04
• Tests explicitly document and enforce this boundary behavior

---

Rationale

• The name MaxVersion implies an inclusive upper bound
• Rejecting Vnn for MaxVersion(n) is surprising to users
• Inclusive behavior aligns with real STIX data usage
• Tests act as executable documentation of intended semantics

---

Tests

Boundary cases are now covered:

• MaxVersion(n) matches Vnn
• MaxVersion(n) rejects versions greater than Vnn
• MaxVersionU follows the same inclusive logic for uncompleted versions

---

Backward compatibility

This change is a bug fix, not a breaking change:

• Existing valid queries continue to work
• Previously failing boundary matches now behave correctly
