Pull request overview

This PR modernizes several Python API/data-model classes by removing redundant private attributes plus trivial property getters/setters, replacing them with direct (typed) attributes and attribute docstrings, and bumps hopsworks-apigen accordingly.

Changes:

• Bump hopsworks-apigen dependency (and build extra) from 1.0.4 to 1.0.5.
• Replace many _x + @property patterns with direct attributes (plus type annotations) across hsfs/hopsworks_common classes.
• Update serialization (to_dict/repr) call sites to use the new attribute names.

schematore_id looks like a typo and introduces a second source of truth for the feature store id alongside _feature_store_id. Because featurestore_id setters/update_from_response_json update schematore_id only, methods that still use _feature_store_id (e.g., alert APIs) can become inconsistent. Use a single attribute for this (prefer _feature_store_id) and have the featurestore_id property read/write that consistently, updating all call sites accordingly.

Suggested change

self.schematore_id = featurestore_id

[Copilot]

The featurestore_id property currently reads/writes schematore_id only, which can diverge from _feature_store_id used elsewhere in the class. After consolidating the backing field, ensure this property remains the single consistent way to get/set the feature store id (including during update_from_response_json).

columns is annotated as plain list, which loses the element type information and undermines the benefit of the newly added attribute type hints. Consider using a more specific type (likely list[str]) and aligning __init__ parameter annotations accordingly so the public API is fully typed.

This change bumps hopsworks-apigen and (based on the diff) alters how user-facing attributes/properties are exposed. The PR description currently doesn’t summarize these user-facing API changes; please update it to explicitly call out the public API impact and the dependency bump rationale.
