[Tests] Add BaseItemBuilder branch coverage tests

[DiamondDagger590]

Summary

• Adds BaseItemBuilderBranchCoverageTest — a comprehensive MockBukkit-based test suite targeting the largest branch coverage gap in the codebase (BaseItemBuilder at 56.4% branch coverage, 96 missed branches)
• Covers 55 test cases across 15 nested test classes exercising previously untested branches: setColor (leather/potion/map/shield/fallthrough), addEnchantment (regular/enchanted book/stored/string resolution), asItemStack (static name/custom name/lore strings/lore components/flags/attribute modifiers/displayNameComponent), setItemDamage, setTrim, setEnchantGlint, hideToolTip/showToolTip, parseComponent, constructors, builder conversions, isEdible, and removeEnchantment by string
• Uses assertDoesNotThrow/assertNotNull assertion patterns consistent with existing ItemBuilderSectionTest since MockBukkit does not support the Paper DataComponentTypes API for state verification

Notes

• Ran testing audit persona and addressed all valid findings: removed duplicate type-check/conversion-throws tests (already covered in BaseItemBuilderTest), fixed misleading getPlainName tests to actually build items before asserting name branches, fixed displayNameComponent test to properly set CUSTOM_NAME on the source ItemStack, added missing isEdible and showToolTip coverage
• All 2167+ tests pass with no failures or regressions

Test plan

• ./gradlew test passes with all tests green
• No regressions in existing test suite
• Testing audit persona reviewed and findings addressed

📝 Walkthrough

Walkthrough

Added a MockBukkit JUnit suite for BaseItemBuilder. The suite covers metadata, enchantments, colors, conversions, parsing, copying, mutations, edible checks, enchant glint, and tooltip states.

Changes

BaseItemBuilder branch coverage

Layer / File(s)	Summary
Core item behavior src/test/java/com/diamonddagger590/mccore/builder/item/BaseItemBuilderBranchCoverageTest.java	Adds MockBukkit setup and tests for names, lore, enchantments, colors, damage, item-stack conversion, component parsing, and constructors.
Item mutations and conversions src/test/java/com/diamonddagger590/mccore/builder/item/BaseItemBuilderBranchCoverageTest.java	Tests trimming, tag replacement, enchantment removal, edible classification, and specialized builder conversions.
Item display states src/test/java/com/diamonddagger590/mccore/builder/item/BaseItemBuilderBranchCoverageTest.java	Tests enchant-glint and tooltip override branches, including repeated and no-op operations.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to f852a

This PR adds branch-coverage tests without changing production behavior. A few assertions are weaker than their test names imply, so regressions could pass unnoticed; the change is mergeable with explicit owner follow-up to strengthen those checks.

568-568: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Assert each specialized builder conversion result.

assertDoesNotThrow accepts a null return. A regression that returns null passes these tests, although each test claims that a specialized builder is returned. Wrap each result with assertNotNull.

• src/test/java/com/diamonddagger590/mccore/builder/item/BaseItemBuilderBranchCoverageTest.java#L568-L568: assert the SkullBuilder result is non-null.
• src/test/java/com/diamonddagger590/mccore/builder/item/BaseItemBuilderBranchCoverageTest.java#L575-L575: assert the PotionBuilder result is non-null.

66-66: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Assert the promised empty value.

Line 66 only verifies that name is non-null. A non-empty result also passes, despite the test name stating that getPlainName() returns empty. Assert name.isEmpty().

Proposed fix

-            assertNotNull(name);
+            assertTrue(name.isEmpty());
