What this PR does / why we need it:

  • Fix init ordering and infinite recursion in SnowflakeRegistry caused by premature attribute access during __init__
  • Fix column casing bugs where Snowflake's uppercase column names broke metadata sync
  • Fix set type hints — use set() instead of [] for set-typed variables in _sync_feast_metadata_to_projects_table
  • Remove leftover private key kwargs (private_key, private_key_path, private_key_passphrase) before passing to snowflake.connector.connect, preventing unexpected keyword argument errors
  • Resolve mypy type errors in SnowflakeRegistry cache methods
  • Correct project_id scoping in get_user_metadata and delete_project
  • Add snowflake_registry fixture to integration registry tests
  • Add comprehensive unit tests for SnowflakeRegistry with xdist_group isolation
  • Add snowflake_registry to CI filter and exclude from non-Snowflake test targets

The UT failures are caused by flaky tests. Can we retry the failed jobs please? Thanks!
