disk usage analysis

Turn noisy du output into actionable storage insights by blending Linux tools (du, ncdu, jq) with an LLM: create compact JSON snapshots, summarize top consumers, diff periodic growth to spot anomalies, and auto-generate a safe, reviewable dry-run cleanup script (journal logs, package caches, containers, language caches). Run locally via Ollama or via API to preserve privacy and build a repeatable “storage health” workflow.
