Smooth Spellblade Compat

1.0.1 - Extra Spell Attributes construction guard

• Fixes a server-start crash caused by Extra Spell Attributes 1.4.0 reading DISSOLUTION while a LivingEntity is still being constructed.
• Handles the Create / Porting Lib entity-size callback path and Moonlight / Supplementaries FakePlayer startup path.
• When the AttributeContainer is not initialized yet, LivingEntity#getAttributeValue(...) temporarily returns the attribute default value instead of dereferencing null.
• The guard only changes the short entity-construction window; normal attribute calculations are untouched after initialization.

Observed crash fixed by this patch: NullPointerException: LivingEntity.getAttributes() is null -> extraspellattributes$getHealthDissolution

1.0.2 - Zenith Attributes Renewed compatibility

• Added an optional compatibility transform for Zenith Attributes Renewed 1.0.3 (zenith_attributes).
• Fixed a client crash while rendering the Attributes GUI with Spell Power 1.6.x.
• Redirects Zenith Attributes' legacy SpellSchool.attribute field access through LegacySpellPowerAccess.attribute(...).
• Keeps the Zenith integration optional; the marker mixin is only applied when zenith_attributes is installed.
• Retains the 1.0.1 Extra Spell Attributes early-construction guard and all previous Spellblades compatibility fixes.
