fix(skills-catalog): stop the unlisted-path section contradicting the state table

Self-review caught it. The section added in eb32c6cc91 opened by calling the
second visibility state "the default outcome of offline authoring". The state
table directly above it says the opposite, and the table is right: a connector
nobody has proven against the provider belongs in the third state,
`availability: { available: false }`, not merely unlisted.

The mechanics were the acceptance finding — nothing enumerated how to take the
second state — and those are unchanged. Only the framing is corrected: the
section now says when the second state is the right one, and points at the
third for the case it was wrongly claiming. Also demotes "do not bump the store
count" out of the numbered list, since the other three entries are edits to
make and that one is not.

Manifest regenerated; validate clean; shipped-catalog 10/10.
