dsh-worklog: DSH Work Log Calendar

The dsh-worklog plugin is designed to address the cumbersome nature of session recording in the DSH environment by providing an automated organization solution. Core features include full session summarization, node-level conversation summaries, support for multiple LLM interface configurations, and generation of reports such as daily and weekly reports. Installation requires Node.js ≥ 22 and supports proactive and manual summary backfilling. Plugin data is stored locally, with a caching mechanism to reduce token consumption, and users can flexibly view details and export reports via the workbench calendar view.
