commit 3f4d03f5a1e811d5d0827260f604451334f5e8ed
Author: 924060929 <[email protected]>

    [refactor](local shuffle) align FE local exchange planning with BE pipeline 
model
    
    Implement FE-side local exchange planning that mirrors BE's native pipeline
    planning (enable_local_shuffle_planner=true). Key changes:
    
    LocalExchangeNode / LocalExchangeTypeRequire:
    - Add LocalExchangeType.isHeavyOperation() mirroring BE 
heavy_operations_on_the_sink()
    - Add LocalExchangeTypeRequire factory methods and autoRequireHash() 
propagation
    - Add shouldResetSerialFlagForChild() override (pipeline split resets 
serial context)
    
    PlanNode (base class):
    - Add enforceAndDeriveLocalExchange() default: noRequire for all children, 
output NOOP
    - Add enforceChild(): enforces exchange on a single child with 
serial-ancestor check
      and heavy_ops bottleneck avoidance (PASSTHROUGH fan-out before heavy 
exchanges on
      serial/pooling scan sources)
    - Add deriveAndEnforceChildLocalExchange(): propagates serial-ancestor 
context
    
    SortNode:
    - mergeByexchange check first; serial+ScanNode child -> requirePassthrough
    - Non-colocated sort above analytic: noRequire/NOOP (parent SortNode 
inserts PT)
    
    TableFunctionNode:
    - Always requirePassthrough from child, output NOOP
    - Models BE's require/output separation: TableFunctionOperatorX overrides
      required_data_distribution() to PASSTHROUGH but outputs unknown 
distribution
    
    AggregationNode (separate commit): mirrors BE three-operator-class model
    
    Tests:
    - LocalShuffleNodeCoverageTest: 13 cases covering all node types
    - LocalExchangePlannerTest: 11 integration cases
    - test_local_shuffle_fe_be_consistency.groovy: 53 cases, all MATCH (0
