[Feature Request]: add support to execute simple bash commands like jq, grep, head

[suryaashish-kubesense]

This make filtering the output much easier, if the data is very large.

Ex

kubectl get pods -A -o wide | grep <node-name>

Don't have an argument against adding filtering in JS, but I think executing bash using pipes may open up for other security issues (see both security advisories were around shell injection: GHSA-gjv4-ghm7-q58q and GHSA-wvxp-jp4w-w8wg).

Ideally this could be some sort of shared "filter" argument that would do the logic for head, tail, grep in JS. JQ would need outputs in a json format, may be a bit more complicated / probably not in initial implementation. Would review a PR with automated tests if filtering done in JS & usable across tools.

Technically this should be offloaded to Agent and LLM. we may introduce max response character and pagination but it will just complicate simplicity of this project. I have seen agent still store entire reponose on local file system and perform subsequent filtering on local file system.
