### Prerequisites

- [x] I will write this issue in English (see our [Language Policy](https://github.com/code-yeongyu/oh-my-opencode/blob/dev/CONTRIBUTING.md#language-policy))
- [x] I have searched existing issues and discussions to avoid duplicates
- [x] This feature request is specific to oh-my-opencode (not OpenCode core)
- [x] I have read the [documentation](https://github.com/code-yeongyu/oh-my-opencode#readme) or asked an AI coding agent with this project's GitHub URL loaded and couldn't find the answer

### Problem Description

Cline Kanban and vibekanban are great, but they are not working perfectly with oh-my-openagent, maybe we could have a Kanban tool just for oh-my-openagent? Like a meta agent(base on Sisyphus) could assign work tree to each column, like we could have Prometheus for planning and Sisyphus/atlas for implementing, or self define column.
Is this possible to make? Boulder system is already great enough, but maybe we could make much more than enough to build the ultimate workflow?

### Proposed Solution

Make a Kanban tool, could be base on existing Kanban tool such as vibekanban, clineKanban
