fix(array-dumper): emit package links and require Link pretty constraint

Resolve the phase-b TODO that left the supported-link-types loop as dead
code (links were always an empty Vec), so requires/conflicts/provides/
replaces/require-dev are dumped again via
PackageInterface::get_links_for_type, matching the PHP magic-call loop.

Every Link in production is constructed with a pretty constraint (all
ArrayLoader/AliasPackage/PlatformRepository/InstalledRepository sites
pass one), so make Link::pretty_constraint a required String instead of
Option<String>. get_pretty_constraint() now returns &str directly rather
than anyhow::Result<&str>, dropping the unreachable
UnexpectedValueException guard, and all call sites are updated.
