Fix regex special character escaping in seatbelt rules for paths with brackets

[ddworken]

Paths containing regex-special characters like [ and ] (e.g., /Users/jbo/Projects/He[ll]o) were not properly escaped when generating macOS Seatbelt regex rules. This caused [ll] to be interpreted as a regex character class (matching a single l) instead of the literal string [ll], so deny rules would not match the actual path.

Fix:

• Escape [ and ] in globToRegex() alongside other regex special characters
• Remove [ and ] from containsGlobChars() so literal paths with brackets use (subpath ...) rules instead of being misrouted through regex
• Fix static prefix extraction in normalizePathForSandbox(), expandGlobPattern(), and generateMoveBlockingRules() to not split on [ and ]
• Drop unused [abc] glob character class support (not used anywhere in this codebase)
• Bump version to 0.0.38
