Pull request overview

This PR aims to fix an issue where NeoForge could not be installed for Minecraft/NeoForge version 26.1.1 when using the official Maven source.

Changes:

• Adjust NeoForge version string parsing to derive the corresponding mcVersion, adding extra validation/logging for unsupported formats.
• Refactor the official API response model from an inner class to a record annotated with @JsonSerializable.

For majorVersion >= 26, this parsing requires a third '.' (si3) and skips the version if it’s absent. Versions like "26.1.1" / "26.1.0" (only 2 dots, optionally with a '+') will be treated as unsupported and never added to the list, which likely reintroduces the install issue. Consider deriving the end of the patch component from the '+' (if present) or string length when no third '.' exists, instead of continueing when si3 < 0.

Suggested change

	int si3 = version.indexOf('.', si2 + 1);
	if (si3 < 0) {
	LOG.warning("Unsupported NeoForge version: " + version);
	continue;
	}
	String ver = Integer.parseInt(version.substring(si2 + 1, si3)) == 0
	? version.substring(0, si2)
	: version.substring(0, si3);
	int separator = version.indexOf('+');
	int separator = version.indexOf('+');
	int patchEnd = separator >= 0 ? separator : version.length();
	String ver = Integer.parseInt(version.substring(si2 + 1, patchEnd)) == 0
	? version.substring(0, si2)
	: version.substring(0, patchEnd);
