DSH-toolfold: A Tool Call Collapse Plugin for DSH Web GUI

dsh-toolfold is an MIT-licensed plugin for DSH Web GUI, designed to reduce interface footprint by collapsing consecutive tool calls. Core features include: automatically collapsing adjacent tool calls to display only summaries and counts, with support for expanding or collapsing via click or keyboard; hiding completed thoughts by default, with configurable options to retain them or separate call groups, while in-progress thoughts remain always visible; supporting elastic animations and performance statistics, along with adaptation to the system's "Reduce Motion" setting. The plugin does not replace the built-in renderer, and the interface fully restores after uninstallation. Install it using `dsh plugin --profile web add dsh-toolfold`, taking effect after restart, and configure animation duration, thought display, separation mode, and statistics toggle via `~/.dsh/settings.yaml`. If the settings service is missing, it degrades to local.
