Report unsatisfied dependencies on add and install

Browse source 
Found while verifying the repo against INTENT.md's eight success criteria for
a first practical release, after CANP-WP-0002 finished.

Criterion 5 is "publish a version to a registry and install it elsewhere".
Installing practice/pqrst-estimate into a fresh catalog reported success, and
rendering it then failed with "included package not found:
practice/house-style". CANP-WP-0002-T03 introduced this — composition made a
package installable but unrenderable, and nothing said so at install time.

The error was honest, but reaching it after a successful-looking install is
the silently-incomplete failure section 23 now names as the thing this format
avoids.

`add` and `install` now name declared prompt dependencies the target catalog
cannot satisfy, including a package present at no matching version. They do
not fetch anything: section 10 leaves dependency resolution to the consumer,
and auto-installing transitively is a resolver — a separate decision from
refusing to hand over a package that looks fine and is not.

Whether `install` should offer `--with-dependencies` is left open as a design
question rather than smuggled in as a bug fix.

Tests 81 -> 84. Recorded as CANP-WP-ADHOC-2026-09-06.
