Conversation compact feature to preserve context among sessions

[non-stop-dev]

Describe the feature or problem you'd like to solve

After fill a model context window truncated message shows forever.

Proposed solution

Would be nice to have the compact conversation feature where it can resume:

• Problems found in the coding session
• Solutions applied
• Problems pending
• Ongoing problem/solution
• Modified/relevant files in the coding session (with relative path)
• Variables changed/created that need to be accounted for
• Relevant documentation (either a webpage explored, a markdown file created by AI or user, etc)

Then reopen a new API call to the model in a fresh conversation with clean context window and pass that summary as initial context for continuation.

/compact command or /summarize if you do not want to name it as other CLI.

Example prompts or workflows

No response

Additional context

No response

I think this would be really useful.

Anecdotally, I often end up starting a fresh new chat in the middle of a task, simply because the context window has grown too large and the quality of the output has diminished.

Compaction shipped in the 0.0.374 release!

@EvanBoyle Is it still possible to get the old truncate behavior with a shell flag?
