dsh-plugin-opencode-bridge: Integrating OpenCode Skills and Configuration into DeepSeek Harness

`dsh-plugin-opencode-bridge` is a DeepSeek Harness (DSH) plugin developed by YYTbit under the MIT license, designed to achieve "zero-migration" bridging between OpenCode and the DSH environment. This plugin primarily addresses the need to integrate existing OpenCode toolchain capabilities into DSH, with core functionalities including automatically loading OpenCode skills (from the path `~/.config/opencode/skills/<name>/SKILL.md`) and injecting configuration context (from the path `~/.config/opencode/opencode.jsonc`). Users can use the `dsh plugin --prof` command to further manage this plugin.
