Subject: [PATCH] feat(coding-agent): added read CLI command for inspecting
 tool output

- Registered a new `read` command in the CLI command registry so `omp read` can be invoked.
- Implemented `runReadCommand` to execute the read tool, wrap it with meta notices, and print text or image-result blocks.
- Added a `read` command class with required path input, optional timeout flag, and usage examples.
