fix(command/show): match PHP null/isset semantics in package output

Three porting mismatches caused show/info output to diverge from PHP:

- "not found" hint appended " in /composer.json" whenever the
  working-dir key existed; PHP uses isset(), which is false for the
  null default. Now only appended when the value is non-null.
- printPackages and generatePackageTree inserted "" for a missing
  description instead of null, so isset() rendered a spurious trailing
  space (and JSON emitted "" instead of null). Both now preserve null.

Un-ignores the eight rendering-gap tests these fix (plus one already
passing), and rewrites the remaining ignore reasons to name the real
blocker (package categorization, --no-dev filtering, RefCell borrow,
installer resolution) instead of a stale generic message.
