/**
* `dsh` default surface — the interactive TUI coding agent. Boots the shipped
* tui-agent config (or an explicit config argument) with the personal overlay
* from `~/.config/dsh`: its `.env` fills environment gaps (precedence: ambient
* environment, then the invoking directory's `.env`, then the personal one)
* and its `config.yaml` patches the booted tree. The workspace is the invoking
* directory: sessions, relative paths, and workspace instructions resolve from
* the cwd, so `dsh` acts on whatever project it is launched in. After boot, the
* agent's system prompt is told the path to this harness checkout so it can find
* its own source.
* @module @deepseek-ai/dsh/tui
