fix(repository-command,config): delimited Preg pattern and list-form repos

RepositoryCommand's JSON-arg detection used the un-delimited regex r"^\s*\{";
the PHP source is the delimited '{^\s*\{}', which compile_php_pattern requires.

Config::merge only extracted repositories from PhpMixed::Array; a JSON array
decodes to PhpMixed::List (an array with integer keys in PHP) and was silently
dropped. Handle List by mapping to integer string keys.

Un-ignores all 10 remaining RepositoryCommandTest cases (16/16 pass).
