Not Enough Calculator

New features:

NEU-Style [NEC] Chat Prefix & Green Formatting (#5):

• /calc chat outputs are now prefixed with a blue [NEC] tag (§9[NEC]) matching NEU calculator formatting.
• Calculation results in chat are now displayed in green (§a).
• Example: [NEC] 1+1 = 2

Number Literal Support (#6 by @ninjaguardian):

• Added support for Binary (0b), Hexadecimal (0x), and Octal (0o) literals:
• Binary: 0b1010 = 10, 0B1101 = 13
• Hexadecimal: 0xFF = 255, 0xa1b = 2587
• Octal: 0o77 = 63, 0o511 = 329
• Underscores allowed between digits: 0b1010_0001 = 161
• Full arithmetic & function support: 0b10 + 0xA + 0o10 = 20, sqrt(0x64) = 10

[NEC] 1+1 = 2
[NEC] 0b1010 = 10
[NEC] 0xFF = 255
[NEC] (0b1101! - 0o6_6^0x5) % 0XAaA0B = 607244

Improvements & Fixes:

• Added @ninjaguardian to fabric.mod.json contributors list.
• Enforced strict token adjacency to prevent spaced inputs (e.g. 0 b10) from misparsing.
• Strict out-of-range digit validation (e.g. 0b102 or 0o78 properly throws an invalid number error).
• Added /calchelp operators entry for number literals.
• Expanded automated test suite to 216 tests covering all literal edge cases and heuristics.
