Add VersionExtensions.ToSemanticString()

[Copilot]

Ports VersionExtensions from CliFx — a ToSemanticString() extension on System.Version that omits the revision component when it is unset.

Changes

• VersionExtensions.cs — new extension; returns version.ToString(3) when Revision <= 0, otherwise version.ToString()
• VersionExtensionsTests.cs — covers no-revision, zero-revision, and non-zero-revision cases

new Version(1, 2, 3).ToSemanticString()    // "1.2.3"
new Version(1, 2, 3, 0).ToSemanticString() // "1.2.3"
new Version(1, 2, 3, 4).ToSemanticString() // "1.2.3.4"
