Refactor EE from enum to class for dynamic Java version support

[Copilot]

The EE enum requires code changes for each new Java release (every 6 months). This refactors it to a class that dynamically creates instances for future Java versions.

Changes

Core refactoring:

• Convert enum EE to final class EE implements Comparable<EE>
• Replace enum constants with static final instances
• Replace EnumSet<EE> with LinkedHashSet<EE> for compatibility tracking
• Add lookup maps (BY_NAME, BY_RELEASE) for efficient retrieval

New API:

// Dynamically create EE for future Java versions
EE ee31 = EE.getOrCreate(31);  // No code changes needed for Java 31+

Preserved API:

• All static instances (EE.JavaSE_17, etc.)
• All public methods (parse(), values(), getEEName(), getRelease(), etc.)
• Comparable behavior for sorting

Breaking changes:

• Switch statements on EE → if-else chains
• EnumSet<EE> → Set<EE> or List<EE>

Version:

• Package version bumped to 5.0.0 (breaking API change)

Example migration

// Before: switch statement
switch (ee) {
    case JavaSE_17 -> handle17();
    case JavaSE_21 -> handle21();
}

// After: if-else
if (ee == EE.JavaSE_17) {
    handle17();
} else if (ee == EE.JavaSE_21) {
    handle21();
}

// Before: EnumSet
for (EE ee : EnumSet.of(EE.JavaSE_17, EE.JavaSE_21)) { }

// After: Set or List
for (EE ee : Set.of(EE.JavaSE_17, EE.JavaSE_21)) { }

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

Refactor the usages of EE enum

The EE class is currently an enum but new java versions aproaching every day

this was tried already to be accounted by extend the enum but this is only a short term solution.

Instead it has to be refactored into a class that allows dynmics changes mas proposed here:
