Point the plugin config at Morrison-Lab/ai-config, add Posit's Quarto skills

[d-morrison]

Why

.claude/settings.json already registered the ai-config plugin, but under the key d-morrison pointing at d-morrison/ai-config. That repo now lives at Morrison-Lab/ai-config, and its .claude-plugin/marketplace.json declares the marketplace name Morrison-Lab — so both the marketplace key and the plugin reference ai-config@d-morrison disagreed with the marketplace they resolve to. The GitHub redirect keeps the clone working, but the plugin's skills (/mwc, /ardi, the PR-workflow skills) did not load in this repo's Claude Code sessions.

What changed

• Renamed the marketplace key to Morrison-Lab, pointed its source at Morrison-Lab/ai-config, and updated the plugin reference to ai-config@Morrison-Lab — matching the install snippet in that repo's README.
• Registered posit-dev/skills (marketplace name posit-dev-skills) and enabled its quarto plugin, which bundles the quarto-authoring, brand-yml, and alt-text skills. This repo is a Quarto website, so those apply directly.

Not enabled, but available from the same marketplace if you want them: posit-dev (general dev skills), github (PR create / review-thread workflows), r-lib (R package development), shiny, connect, open-source, ggsql.

Verification

.claude/settings.json parses as JSON; the marketplace keys and plugin references match the name fields in each upstream .claude-plugin/marketplace.json (Morrison-Lab and posit-dev-skills). Plugin loading itself only takes effect in a fresh session, so it can't be exercised from this one.

All unrelated to the plugin marketplace config — different repos (qwt, psw itself, rme) that are out of scope for this PR. No cleanup needed there.

The change itself is minimal, correct, and well-scoped: it renames the marketplace key to match the actual marketplace.json name at Morrison-Lab/ai-config, updates the plugin reference to match, and additively registers posit-dev/skills with the quarto plugin enabled. I independently verified every factual claim in the PR description against the live repos:

• d-morrison/ai-config 301-redirects to github.com/Morrison-Lab/ai-config (repo was renamed/transferred).
• Morrison-Lab/ai-config's .claude-plugin/marketplace.json declares "name": "Morrison-Lab", matching the new key.
• posit-dev/skills's marketplace.json declares the marketplace name posit-dev-skills and defines a quarto plugin bundling brand-yml, quarto-authoring, and alt-text — exactly as described, and directly relevant since this repo is a Quarto website.
• The resulting .claude/settings.json is valid JSON.

No .qmd chapters, prose, citations, or Quarto config are touched by this PR (it's confined to .claude/settings.json), so the SERG lab-manual prose/coding-style/practices sections don't apply here — this is tooling/CI configuration, not R or Quarto content. No hallucinated APIs, packages, or URLs were found.

One neutral observation (not a blocker): I noticed the local working tree has an unstaged, uncommitted reversion of this exact file back to the pre-PR content — this is local session/environment state, not part of the PR's committed diff, so I did not treat it as a finding and left it untouched per review-only instructions.
