docs(skills): rewrite container-security descriptions to a uniform standard

All 33 container-security skills now carry what it does, an explicit
"Use when" trigger, keywords, and a negative trigger naming the nearest
neighbour. Six collision clusters resolved by differentiating scope
rather than merging, so no skill is removed:

- kube-bench: running the tool vs interpreting findings into an audit
- Calico: portable upstream NetworkPolicy vs Calico-as-CNI vs Calico-only
  CRDs (GlobalNetworkPolicy, HostEndpoint, DNS egress)
- Falco: deploying and operating it vs authoring escape rules
- container escape: tool-agnostic runtime signals vs Falco rule syntax vs
  static posture audit vs offensive breakout
- Trivy: all-target platform and operator vs single-image scan
- Docker: images and Dockerfiles vs daemon.json vs the CIS audit script

Also replaces the templated "When to Use" boilerplate in these files,
including bullets that only restated the skill's own name.

Worst pair (Pod Security Standards vs Pod Security Admission) drops from
0.77 cosine to below the 0.45 threshold. Repo-wide: colliding pairs
60 -> 56, skills involved 105 -> 94.

description: >-
Parses Kubernetes API server audit logs (JSON lines) to detect exec-into-pod, secret access,
RBAC modifications, privileged pod creation, and anonymous API access, and builds SIEM
detection rules from the event patterns. Use when investigating a suspected cluster
compromise, reconstructing what an attacker did through the API server, or writing
Kubernetes-specific detection content. Keywords: audit policy, audit log, kube-apiserver,
exec into pod, RBAC change, anonymous access, detection rules. Do not use for syscall-level
detection inside a running container - use detecting-container-runtime-threats-with-falco.
