Added support for DQLPart language

[dorian-krefft-dt]

The language is a better option than the DQL file name part as it is much easier to disable some parts of the language feature support when the file type is different.

Also, it allows to specify that this is a partial file for IntelliJ annotations:

public class Example {
    public static final String BASE_QUERY = /* language=DQL */ """
            fetch events, bucket: {"my-bucket"}, from: -1h
            """;

    public String generateQuery(boolean withFilter) {
        String query = BASE_QUERY;
        if (withFilter) {
            query += /* language=DQLPart */ """
                      | filter event.provider == "my-provider"
                    """;
        }
        return query;
    }
}

Pull request overview

Adds a dedicated DQLPart language/file type (.dqlpart) to better support DQL query fragments (e.g., for string injection / dynamic query building), and introduces migration tooling away from legacy *.partial.dql naming.

Changes:

• Register new DQLPart language + file type and reuse DQL lexer/parser/highlighting infrastructure for fragments.
• Add an inspection + quick-fix to migrate .partial.dql suffix usage to .dqlpart.
• Update existing inspections/docs/changelog to reference the new .dqlpart approach.
