What would you like to be added?

Feature hasn't been suggested before.

I have verified this feature I'm about to request hasn't been suggested before.

Describe the enhancement you want to request

Currently, qwen-code automatically generates a session ID when starting a new session. While this works well, it makes it difficult to organize or intentionally resume sessions for specific projects.

I would like to request support for manually specifying a session ID when launching qwen-code, similar to how OpenClaw allows custom session identifiers.

Example
qwen-code --session my-project

With this feature, users could:

Start a session with a meaningful name
Resume the same session later using the same session ID
Organize multiple projects more easily
Avoid relying only on auto-generated session IDs
Example workflow

Start a session:

qwen-code --session my-project

Later resume the same session:

qwen-code --resume my-project

Why is this needed?

Benefits
Better project-based session organization
Easier session recovery
More predictable workflows when using qwen-code for multiple tasks
Improved scripting and automation possibilities

This feature would be especially useful for developers who use qwen-code across multiple repositories or long-running development sessions.

If session IDs are currently auto-generated internally, this could potentially be implemented as an optional override flag while keeping the current default behavior unchanged.
