feat: add support for flow config fields in liquid lsp

[Gasser-Aly]

What are you adding in this PR?

This PR adds support for URI-scoped object definitions in the theme language server. The implementation allows objects to be registered and retrieved on a per-URI basis, enabling more granular control over which objects are available in different contexts.

The key changes include:

• Added getObjectsForURI method to the ThemeDocset interface as an optional method
• Implemented URI-based object storage in AugmentedThemeDocset with both exact and prefix matching capabilities
• Modified the UndefinedObject check to use URI-specific objects when available
• Updated the TypeSystem to consider URI context when building object maps and symbol tables
• Added a new SetObjectsNotification to allow clients to register objects for specific URIs
• Removed memoization from object-related methods that now depend on URI context

This enables different files or paths to have different sets of available objects, which is useful for context-specific Liquid environments.

What's next? Any followup issues?

The implementation provides the foundation for URI-scoped objects. Follow-up work might include:

• Documentation on how to use the new URI-scoped object functionality
• Testing with real-world scenarios to validate the prefix matching behavior
• Potential performance optimizations if the object lookup becomes a bottleneck

What did you learn?

The prefix matching implementation allows for flexible URI-based scoping where you can register objects for a base path and have them apply to all files within that path hierarchy. This provides a good balance between specificity and maintainability.
