 fix: make SemanticVersionRange equality structural 
The type was a record struct whose ==/Equals/GetHashCode were
synthesized from all fields, including the _sets array, so two
ranges that parse to the same constraint sets compared as
unequal (reference-sensitive on the array). This also broke
using ranges as dictionary keys, where lookup relies on value
equality.

Change the type to a plain readonly struct implementing
IEquatable<SemanticVersionRange> with structural equality over
the constraint sets (operation + version per comparator). The
custom ToString already existed, so no display behaviour is lost.

Add a failing-then-passing test.

1.0.0 - 2026-05-21

Added

  • This is the initial release of the library.

Unreleased

Added

Changed

  • SemanticVersion ==/Equals/GetHashCode now ignore build metadata, matching precedence comparison rules.
  • SemanticVersionRange equality (==, Equals, GetHashCode) is now structural and based on the constraint sets, so ranges that parse to the same comparators compare as equal (previously it was reference-sensitive on the backing array).

Fixed

  • Reject invalid SemVer identifiers when parsing versions.
  • Range exact and non-equal comparators ignore build metadata when matching versions.
  • Avoid infinite recursion when formatting ranges in the short npm (ns) form.
