dsh-obsidian-channel: Securely Read and Write a Local Obsidian Vault via DeepSeek Harness

The `dsh-obsidian-channel` plugin is designed to mitigate the risk of data loss caused by DeepSeek Harness (DSH) agents directly manipulating a local knowledge base. It provides the DSH Agent with a controlled channel, enforcing user approval for all read and write operations, and supports viewing change history and one-click rollback. Its core features include secure approval, change tracking, Vault homepage management, and read/write isolation. Users must first install the dsh web environment and bind the Obsidian Vault path, then start a session via the homepage, confirm the content in the editor before sending, and the Agent requests approval again before executing any write. Although the plugin can effectively prevent accidental deletion, users should remain alert to the risk of Bash commands bypassing the Journal mechanism. The plugin does not currently support templates.
