Fix GitHub issue #132: Standardize varargs JavaDoc terminology

Standardized JavaDoc terminology and fixed grammar errors when describing
varargs parameters across the codebase.

**Changes:**
- "var args" → "format arguments"
- "var arg" → "format arguments"
- "thats" → "that are" (grammar fix)

**Files updated:**
- AbstractBase.java: 17 occurrences fixed
- LoggerUtil.java: 13 occurrences fixed

**Benefits:**
- Consistent terminology throughout documentation
- Fixed grammar errors (missing apostrophes)
- Clearer documentation following Java standard library style
- Describes what parameters ARE (arguments) not implementation (varargs)

All 265 tests pass with 100% coverage maintained.
