Feature: Support Displaying Runtime Filters in EXPLAIN Output

[zhang2014]

Summary

Currently, the EXPLAIN output doesn't explicitly show the runtime filters that are applied during query execution. Displaying runtime filter information would significantly help in:

• Analyzing query performance optimization
• Understanding filter propagation between scan nodes
• Debugging query execution efficiency

Proposed Solution:

Add runtime filter information to EXPLAIN output including:

• Applied runtime filter identifiers
• Filter types (IN/BLOOM_FILTER/MIN_MAX etc.)
• Source expressions/tables
• Target scan nodes
• Filter effectiveness statistics (optional)
