  1. Add exception tracking with node backtrace (fixes #990) 

    When an exception is thrown during tick(), it is now wrapped in a
NodeExecutionError that includes:
- The failing node's name, path, and registration name
- Full tick backtrace from root to the failing node
- Original exception message

This helps users debug which node caused an exception during tree
execution, addressing the feature request in issue #990.

Example output:
  Exception in node '/MainTree/Seq/MyAction': Connection timeout
  Tick backtrace:
     /MainTree (RootNode)
     /MainTree/Seq (Sequence)
  -> /MainTree/Seq/MyAction (MyCustomAction)
