The version (4.0.1 -> 4.0.2 in CurrentVersion.cs and CurrentVersion.props), the release notes in Docs/releases/v4.0.2.md, and the README links for IronRuby 4.0.2, as for 4.0.1 (6da13f3).

Once this is merged, pushing the tag v4.0.2 builds the three archives, attests them and SHA256SUMS, and publishes the release with these notes. The download links in the README work from then on.

Walkthrough

This PR marks IronRuby 4.0.2 in version metadata, adds release notes, and updates README release references. It also changes Windows file-lock platform detection, scopes the original certificate in the Windows PFX round-trip, and makes the Range serialization constructor private.

Changes: 4.0.2 release information

Layer / File(s) Summary
Set the 4.0.2 version
CurrentVersion.props, Src/Ruby/CurrentVersion.cs
The micro version and public version strings change from 4.0.1 to 4.0.2. The assembly version remains unchanged.
Update release references and notes
README.md, Docs/releases/v4.0.2.md
The README links to the 4.0.2 downloads and release notes, updates version examples, and describes archive names and provenance. The new release notes cover release contents, reported changes, acknowledgments, and known limits.

Windows file-lock selection

Layer / File(s) Summary
Select file-lock implementation by operating system
Src/Libraries/Builtins/FileOps.cs
FileLock now uses OperatingSystem.IsWindows() to select the Windows implementation. WindowsFileLock is annotated as supported on Windows.

Windows PFX certificate handling

Layer / File(s) Summary
Scope the original certificate lifetime
Src/Libraries/Puma/MiniSsl.cs
The Windows PFX round-trip exports from the named ephemeral certificate in both framework branches. The loaded certificate remains assigned to leaf, and the original is disposed when its scope ends.

Range serialization constructor

Layer / File(s) Summary
Make the serialization constructor private
Src/Ruby/Builtins/Range.Subclass.cs
The serialization constructor changes from protected to private. Its comments describe the class data in SerializationInfo and private-constructor discovery.

Explanation

Docstring coverage is 66.67% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 3 functions across 4 files. (3 skipped: 3 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Comment @coderabbitai help to get the list of available commands.

- FileOps.cs (CA1416): flock tells Windows by OperatingSystem.IsWindows(),
  which the platform analyzer understands, and WindowsFileLock is marked
  SupportedOSPlatform("windows"), so its NativeOverlapped is no warning.
- MiniSsl.cs (CS0728): the PFX round trip no longer assigns to the variable
  of its using statement; the ephemeral certificate has a name of its own,
  and is still the one disposed.
- Range.Subclass.cs (CS0628): the serialization constructor of the sealed
  type is private, as for any sealed ISerializable type.

The Debug build of the console has no warnings now on net8.0 and net10.0;
the full C# suite passes.
