Feature request: /export-all that includes the whole content of a session, and is not limited by compaction or terminal buffer limit

[lukstafi]

Due to terminal buffer limits, it is easy to lose session logs for longer tasks. /export only includes context since the last compaction and moreover without the compaction's summarization, and the terminal only retains so much.

Note: I haven't explored increasing the terminal buffer size on the OS side of things; that might be a workaround.
