Obsidian Catalog: Moving the Obsidian Vault Directory into the DSH Session View

Obsidian Catalog (dsh-plugin-obsidian-catalog) is a DeepSeek Harness bundle written by maintainer scy88866-beep that renders an Obsidian vault into a real-time directory panel within the chat view: The host side reads directly from the disk, grouping notes by folder to display titles, word counts, relative modification dates, tags, and outlines of the first three heading levels. Both note rows and folder rows feature one-click copying of absolute paths with the "@" symbol. Vaults can be switched within the panel with the selection remembered; for unchanged notes, it uses mtime+size caching and refreshes via polling every 15 seconds. Installation is performed using `dsh plugin --profile web add dsh-plugin-obsidian-catalog`, requiring DSH 0.2.x; vaults are resolved by default using the configuration file, the `DSH_OBSIDIAN_VAULT` environment variable, or `<home>\obsidian`. The plugin runs with current process permissions and accesses the vault in read-only mode, with a scan limit of 12 directory levels and 5,000 markdown files.
