fix(ingest/snowflake): Skip sql parsing if all the features disable in config where it is needed

Optimize Snowflake Ingestion: Skip Query Fetching When All Features Disabled

Problem

When running Snowflake ingestion with all query-based features disabled, the ingestion process was still:

• Fetching queries from Snowflake's query_history and access_history tables
• Parsing and fingerprinting each query
• Taking several minutes to process queries that would never be used

This happened because the feature flags (include_lineage, include_queries, include_usage_statistics, include_query_usage_statistics, include_operations) only controlled what output was
generated, not whether to fetch queries in the first place.

Example Configuration Affected

source:
  type: snowflake
  config:
    include_table_lineage: false
    include_queries: false
    include_usage_stats: false
    include_query_usage_statistics: false
    include_operational_stats: false
    include_views: true
    # ... other settings

Users would see 'num_preparsed_queries': > 0 in logs even though all query features were disabled.

Solution

Added a conditional check in SnowflakeQueriesExtractor.get_workunits_internal() (lines 300-322 in snowflake_queries.py) that evaluates whether any query-based features are enabled before executing
expensive Snowflake queries:

needs_query_data = any([
    self.config.include_lineage,
    self.config.include_queries,
    self.config.include_usage_statistics,
    self.config.include_query_usage_statistics,
    self.config.include_operations,
])

if not needs_query_data:
    logger.info("All query-based features are disabled. Skipping expensive query log fetch.")
else:
    # Fetch copy history and query log..

LGTM, in next step, let's try to limit amount of flags used to calculate needs_query_data.
