Release 0.4.0

Added

• Measure-GremlinCharacter: New rule to detect invisible or visually
  deceptive Unicode characters (gremlins) such as zero-width spaces,
  bidirectional overrides, and curly quotes. 19 characters flagged with
  per-character severity (Error, Warning, or Information).
  Inspired by vscode-gremlins.
• Tests for Measure-GremlinCharacter with per-character -ForEach
  cases, a negative clean-code case, a fixture-based detection test,
  and a suppression test using SuppressMessageAttribute.
• CLAUDE.md with project guidance for Claude Code.

Changed

• Measure-TODOComment: Updated Token parameter type to Token[]
  to match how PSScriptAnalyzer invokes token-based rules; renamed
  $matches to $regexMatches to avoid collision with the automatic
  $Matches variable; normalized keyword casing to lowercase.
• tests/PSScriptAnalyzerRules.psm1: Proxy module now loads explicitly
  from the Output\GoodEnoughRules build directory.
