fix: add markdownlint config and auto-fix markdown errors
- Add .markdownlint-cli2.jsonc based on headlamp-agent-skills config
- Disable MD013 (line length), MD041 (first-line-heading), MD036
(emphasis-as-heading), MD024 (no-duplicate-heading), MD040
(fenced-code-language), MD060 (table-column-style), MD029
(ol-prefix), MD033 (no-inline-html) — appropriate for plugin docs
- Run markdownlint-cli2 --fix to auto-fix MD022, MD031, MD032
- Manually fix remaining code block language annotations
