Pull Request Overview
This PR adds functionality to collapse process tree entries by default, providing both command-line and configuration file options to control this behavior. The implementation introduces a new TreeCollapsed enum that handles both default-collapsed and default-expanded states, replacing the previous simple HashSet<Pid> approach.
Key changes:
- Introduction of
TreeCollapsedenum to manage collapse/expand state with different default behaviors - Addition of
--tree_collapsecommand-line flag andtree_collapseconfig option - Refactoring of process tree logic to use the new state management system
