[Feature]Identify all dependencies on the legacy pipeline outside of next.query.kgram.

[abdessamad-abdoun]

Identify all dependencies on the legacy pipeline outside of next.query.kgram.

Classify each dependency as one of the following:

• A legitimate bridge dependency on types understood by KGRAM.
• An unintended leak to the parser, AST, or public API.
• A temporary dependency that can later be replaced with a next type.

Keep all required conversions within impl.sparql.bridge.

Remove dependencies from the AST and the parser to the legacy pipeline.

Do not modify KGRAM or redesign StorageManager as part of this task.
