refactor(workspace): split monolithic crate into 6 workspace crates

Extract modules from the single `mozart` crate into 5 focused library
crates to improve compilation parallelism and architectural clarity:

- mozart-constraint: version constraint parser (independent)
- mozart-core: base types, console, validation, platform utilities
- mozart-archiver: archive creation (tar, zip, bzip2)
- mozart-registry: Packagist API, cache, resolver, downloader, lockfile
- mozart-autoload: autoloader generation and PHP scanner

Refactor Console::from_cli and build_cache_config to accept primitive
args instead of &Cli to break circular dependencies. Introduce
[workspace.dependencies] for centralized version management. Remove 9
unused direct dependencies from the CLI crate.
