…query

The old masthead required custom label configuration and was specific to
ML/GPU workloads. The new example needs no configuration, joins pods and
nodes to show per-node memory pressure, uses the synthesized status column
to catch init-phase pods, and includes a working kubectl+jq equivalent that
honestly illustrates the footguns: pipe-scope bugs, argv overflow on large
clusters, memory suffix parsing, and the absence of to_size() formatting.

- -c/--cache → -s/--stale
- -u/--update → -r/--refresh
- -r/--reckless → -q/--quiet (and reckless: → quiet: in settings)
- -c is now free for --context (Kubernetes context switching)

Pass -c/--context to KubernetesResource so kubectl calls include
--context <name>, and use it as the cache path prefix instead of
reading the active kubeconfig context.

Replace ^ parent-hop syntax with named scope references. Multi-step
row_source entries must carry 'as <name>', and column paths/labels must
be prefixed with a declared scope name. Single-step tables are unchanged.

Centralizes the scope-prefix detection logic that was inline in
UserColumn.rebuild_for_scope, making FieldRef the single place
responsible for splitting a scoped expression into name + target.

Mirrors the 'as <name>' suffix in row_source declarations — 'as' binds,
'in' references. Eliminates ambiguity when scope prefixes and label DNS
domains collide (e.g. 'pod.karpenter.sh/nodepool').

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Replace ^ parent-hop syntax with as/in named scope syntax throughout
docs and CLAUDE.md; add from: auto-detection description; bump CHANGELOG
to 0.9.0.
