add chart crds to human plan view

[atkrad]

Summary

• Human plan output now has a Chart CRDs section after Resources and before Tasks.
• Each entry shows the chart CRD name, source file, and Helm lifecycle: process on install, skip when install-time processing is off, or upgrade when Helm will not process the chart CRD.
• Chart CRDs stay out of the resource summary. JSON output is unchanged. The public deployah plan command still uses the legacy renderer, so CLI docs are unchanged.

Test plan

• Unit tests added/updated
• Scenario under scenarios/ (if behavior changes)
• nix run .#lint / pre-commit clean
• Manual smoke (command + expected result), if user-facing

Labels

• One of: kind/feature, kind/bug, kind/docs, kind/chore
• Add breaking-change if this breaks existing CLI or config behavior
• Add skip-changelog for internal-only PRs that should not appear in notes

Checklist

• Title is short and imperative (matches commit style)
• Docs / CLI help updated when user-facing (README.md, docs/cli/)
• No secrets or local-only paths in the diff
