can1357 53276368cb feat(coding-agent): redesigned the Todo HUD as a connector tree
- Redesigned the Todo HUD as a connector tree with fixed-budget stage previews.
- Anchored status and HUD containers to prevent redundant UI elements in terminal scrollback.
- Implemented tree-based rendering for project phases and tasks while removing dynamic border rules.
- Upgraded `sherpa-onnx` and related packages to support current infrastructure.
