Not Enough Calculator (REI Search Bar Calculator)

New features:

Live Syntax Highlighting:

• Numbers & Decimal values: Pure Bright White (§f)
• SkyBlock Units (k, m, b, t, s, e, h, sc, dc, eb): Vibrant Cyan (§b)
• Math Functions (sqrt, bz, ah, fmt, rad, deg, etc.): Bright Yellow (§e)
• Built-in constants (ans, pi, e) and custom variables ($var): Bright Green (§a)
• Math Operators (+, -, *, x, /, ^, %, !, &, |, ~, <<, >>): Bright Gold (§6)
• Delimiters & Parentheses ((, ), ,): Light Gray (§7)

Custom Variables Manager GUI Tab:

• Added a new GUI tab in /calcconfig to easily add, edit, delete, and paginate (< / >) custom variables in-game.

Focus-Aware Search Bar Border:

• Search bar border dynamically switches to Pure Bright White (0xFFFFFFFF) when actively typing/focused, and Unfocused Gray (0xFF8B8B8B) when unfocused.

Improvements & Fixes:

• Centralized all color codes in SyntaxHighlighter.java.
• Centralized math functions (FUNCTIONS), unit multipliers (UNITS), and built-in constants (BUILTIN_VARIABLES) in ExpressionEvaluator.java.
• Token regex patterns in SyntaxHighlighter.java and CalculatorManager.java are fetched dynamically from ExpressionEvaluator. Adding a new unit or function now updates evaluation, autocompletion, regex matching, and syntax highlighting.
• Refactored ResultFormatter to reuse cached ExpressionEvaluator.UNITS BigDecimal instances, eliminating temporary object allocations during render loops.
• Added new test coverage for syntax highlighting token rules (325+ total unit tests).
