Reconcile the docs/ tree to the duxt page contract

[TitusKirch]

What problem are you trying to solve?

.tituskirch-skills.json now declares docs.render: duxt, but the existing docs/ tree was written under the portable contract. Today 5 pages open with a body H1, 3 link with relative .md paths, and the tree contains no ::page-cards and no ::callout. The config and the tree contradict each other, and the tree is the half that is wrong.

Proposed solution

Run the write-docs reconcile sweep over docs/ so the tree matches the contract it declares. Settled up front:

• Preset package stays — no sections added, renamed or removed. This is not a restructuring.
• The five duxt page rules apply — no body H1, absolute doc paths, ::page-cards in a section index, theme frontmatter fields, ::callout for the status marker.
• Prose is not rewritten. This is a contract fix. Hand-written content stays as it is, word for word, except where a rule above touches it.
• Language en, unchanged.

Alternatives considered

Dropping docs.render again and staying portable. Rejected: duxt is the declared rendering target for this estate's docs trees, and kirchDev/duxt's own tree already sits in that contract — it is the reference for what the result should look like.

Additional context

Counts at the time of writing: 5 markdown pages, 3 with relative .md links, 0 ::page-cards, 0 ::callout.

Acceptance: no page carries a body H1, doc links are absolute, section indexes use ::page-cards, the status marker uses ::callout, and a diff shows no prose change beyond what those rules require.
