Expose `--limit` / `--offset` on list commands

[patrikbraborec]

Summary

Without --limit and --offset, agents get unbounded data which wastes tokens and causes confusion.

Action Items

• Add --limit and --offset flags to all list commands
• Ensure sensible defaults for both interactive and programmatic usage

I'm a bit confused if this is actually missing from somewhere or its just... to verify everything 👀

[patrikbraborec]

Good point. I checked it, and all 8 list commands already have --limit and --offset:

Command	--limit	--offset
actors ls	✅	✅
actors search	✅	✅
builds ls	✅	✅
datasets ls	✅	✅
datasets get-items	✅	✅
key-value-stores ls	✅	✅
key-value-stores keys	✅	N/A*
runs ls	✅	✅

* key-value-stores keys uses --exclusive-start-key (cursor-based pagination) instead of --offset.

Everything is already in place. I will close the issue for now, and if we see any error with the current approach, let's reopen it.
