Add the catalog index, and package a real prompt collection

CANP-WP-0004. The operator asked canned-prompts to build a database of
versioned prompts recording where each came from and when — the first step
toward a platform for collaborative prompting.

The format had nowhere to put that. `provenance` records who wrote a prompt and
where the idea came from; nothing recorded how a copy arrived in a particular
store. Section 20.3 now specifies an `index.yaml` as store metadata rather than
package data: how a copy arrived differs for every consumer, and recording an
arrival must never rewrite the package that arrived.

`add`, `install` and `publish` record registry, id, version, name, source,
method, first-inclusion date, and the package's declared author, source and
licence — the last three copied so a listing is readable without opening every
package. A new `index` verb lists it. `included_at` is never overwritten; a
re-run updates `last_seen_at`, because when a package first entered a
collection is a fact about history rather than about the last command run.

Tests 84 -> 90.

Also records two findings from actually using the format:

CANP-WP-0004-T03 — inclusion has no deduplication, so a diamond dependency
renders shared content once per path. Found by composing a real collection.
Not fixed here: deduplicating means choosing which occurrence survives and
deciding what happens when two paths resolve different versions, which is
resolver behaviour that section 10.4 deliberately avoids. Handed to
CANP-WP-0005 with a leaning: document it, warn at validation time, do not
deduplicate.

The add_ons workaround in practice/pqrst-estimate is evidence about section
23's deferred "richer template syntax" — an optional appendix has to be an
input with an empty default, because CPF has no conditionals.

- `add` and `install` name declared prompt dependencies the catalog cannot
satisfy. They do not fetch them — resolution is the consumer's job (§ 10) —
but a package that looks installed and cannot render should say so.
- `add`, `install` and `publish` record an entry in the store's `index.yaml`:
source, method, first-inclusion date, and the package's declared author,
source and licence. `index` lists it. Re-adding keeps the original
`included_at` and updates `last_seen_at`.
- An optional `registry.yaml` names a registry and records namespace claims.
`publish` warns when a namespace is declared `closed` — it cannot
authenticate a publisher, and says so rather than implying it checked.
