[FEATURE] automatic compression of session logs (~/.claude/projects/*.jsonl) to save disk space

Preflight Checklist

Problem Statement

My session logs are quite large - beginning to fill up my travel laptop - and I don't want to purge them. Can they perhaps be stored compressed, and have claude decompress on-the-fly?

(instead/additionally, perhaps a periodic process to automatically convert session logs into more compact memory?)

Proposed Solution

I'd like claude to:

1. store jsonl files as compressed files, so they take up less log space (sharding them would likely help with this as well)
2. periodically rewrite session logs as memory, so it can take up less space.
