feat: Add disk usage percentage and warn on high usage - #57
Merged

The tracing statement for `user.gid` was reading from `user.uid` instead of `user.gid`, causing the wrong value to be reported.
Replace `into_iter().next().is_none()` with `list().is_empty()` for clarity, and use `list().iter()` for the actual collection.
This was likely a debugging leftover — the error source chain is already captured via the `successors` iterator below.
JSON serialization and file write can fail at runtime (e.g. disk full). Log the error and continue the loop instead of crashing, since this tool may run continuously for hours.
std::thread::sleep blocks the entire tokio worker thread. Since main is already async, use the non-blocking alternative.
In a container debugging tool, broken DNS config (/etc/resolv.conf) is a likely scenario to diagnose. Log the error and skip DNS lookups instead of panicking.
…andling The network collector silently swallowed interface listing errors by returning empty data. Now it returns Result so the orchestrator wraps it in ComponentResult, matching the pattern used by other fallible collectors. Errors appear in JSON output instead of being silently lost.
HashMap produces non-deterministic JSON output, making it hard to diff containerdebug output across runs. BTreeMap sorts keys consistently.
Add `usage_percent` field to disk collection output. When a disk exceeds 85% usage, log at WARN level instead of INFO so it stands out in log aggregation systems.
