Add .markdownlint-cli2.jsonc to suppress MD013 (line-length) and MD041
(first-line-heading) which are inappropriate for agent skill files with
YAML frontmatter and code examples.
Fix genuine structural issues in all affected files:
- Add blank lines around headings (MD022)
- Add blank lines around fenced code blocks (MD031)
- Add blank lines around lists (MD032)
- Add language specifiers to bare code fences (MD040)

Covers ArtifactHub's pull-based model, metadata files
(artifacthub-repo.yml, artifacthub-pkg.yml), Headlamp-specific
annotations, and the release-to-publish pipeline. Corrects common
misconceptions about pushing/reconciliation.
