fix: inject APP_NAME/APP_VERSION and populate Composer\InstalledVersions in Debian autoloader

- debian/control: add composer as first Depends (or replace composer-debian)
  to guarantee /usr/share/php/Composer/InstalledVersions.php is present
- debian/autoload.php: require InstalledVersions.php and call reload() to
  accumulate per-package data across chained autoloaders; APP_NAME/APP_VERSION
  constants pin the root package identity
- debian/rules: inject guarded defined()||define() constants at build time
  using PKG_SOURCE/PKG_VERSION from dpkg-parsechangelog
