Adds a `mozart-php-serialize` crate (a byte-compatible port of PHP's
`serialize()`) and a `mozart-registry::path_repository` module that
expands `type: path` entries into synthetic `type: package`
repositories. Each synthesized package carries the same SHA-1 dist
reference Composer computes (`sha1(\$json . serialize(\$options))`)
so the lockfile and trace lines match Composer byte-for-byte.
Two latent bugs surfaced once the path-repo flow exercised real
resolutions:
- `apply_partial_update` swapped path-repo packages back to their
locked version, defeating Composer's "path repos always reload"
rule (`PoolBuilder` treats them as canonical, not lock-bound).
Mirror the path-repo skip already used when constructing
`locked_packages`.
- `normalize_root_alias_atom` returned the raw input string for
stable numeric atoms (e.g. `1.1.1`), so the alias matcher's
`input.version \!= alias.version_normalized` check — comparing
against pool inputs that carry the 4-segment normalized form —
silently never matched. Run the parsed Version through Display so
both sides are in the same shape.
`install/update::run` gain a `path_repo_base_override: Option<&Path>`
parameter for the in-process test harness: Composer's PHPUnit
`InstallerTest::setUp` does `chdir(__DIR__)` so relative path-repo
URLs resolve against `composer/tests/Composer/Test/`, but the Rust
harness writes `composer.json` into a per-test tempdir and can't
chdir safely under parallel tests. Production callers pass `None`
and resolve against `working_dir`.
Greens 3 ignored installer fixtures:
partial_update_loads_root_aliases_for_path_repos
alias_in_lock
alias_in_lock2

Adopt indexmap workspace-wide so iteration order is deterministic and
follows insertion order. The non-deterministic order of std HashMap
otherwise leaks into resolver decisions when multiple valid solutions
exist (e.g. cyclic require pairs under prefer-lowest), making behavior
flaky and divergent from Composer's PHP-array semantics.

Sets up DI scaffolding for in-process installer E2E tests, mirroring how
Composer's PHPUnit suite swaps Packagist (FactoryMock) and the install
manager (InstallationManagerMock) without touching the network or filesystem.
Additions:
- Repository trait + RepositorySet (Composer's RepositoryInterface analog),
with PackagistRepository, InlinePackageRepository, VcsRepository impls.
- InstallerExecutor trait (Composer's InstallationManager analog) with
FilesystemExecutor extracted from install_from_lock.
install_from_lock now delegates per-package install/uninstall verbs to
FilesystemExecutor; console output orchestration stays in the caller so
existing --EXPECT-OUTPUT-shape assertions remain comparable. No behavior
change - all 136 enabled installer fixtures still pass.
Also tightens the installer_fixture\! ignore form to a single token
(installer_fixture\!(name, ignore)) for readability.

Add per-fixture #[test] entries (187 total) via a small declarative
macro that reads files directly from the composer submodule. For now
each test only asserts the file parses; execution and EXPECT-* checks
will be layered on as the harness gains comparison helpers.

Implement VCS driver/downloader infrastructure mirroring Composer's VCS
subsystem. Includes drivers for GitHub, GitLab, Bitbucket, Forgejo, Git,
Hg, and SVN with API-based metadata resolution, plus source downloaders
for Git/Hg/SVN. Integrates into mozart-registry via vcs_bridge module to
scan VCS repositories and feed discovered packages into the SAT resolver.

Replace two-line output (name+counts, indented description) with
Composer's single-line aligned format: padded name, abandoned warning,
and terminal-width-aware description truncation. Remove summary header
and download/faver count display from text output.

Replace simple prefix check in is_valid_url with url::Url::parse() for
structural validation (e.g. "https://" with no host now correctly
rejected). Update Windows open_browser to use `start "web" explorer`
matching Composer's HomeCommand behavior.

Introduce a Symfony Console-style tag macro that replaces verbose
patterns like `console::info(&format!("text {name}"))` with
`console_format!("<info>text {name}</info>")`. Supports all 6 tag
types (info, comment, error, question, highlight, warning) with
format argument distribution across multiple tagged segments.

Add mozart-sat-resolver crate implementing a CDCL SAT-based dependency
resolver ported from Composer's DependencyResolver. This replaces the
pubgrub library to ensure identical resolution behavior with Composer.
The new crate includes: pool (package storage with integer IDs),
rule/rule_set/rule_set_generator (constraint encoding), decisions
(assignment tracking), rule_watch_graph (2-watched literal BCP),
solver (CDCL loop with conflict analysis and clause learning),
policy (version preference), problem (Composer-style error messages),
and transaction (install/update/uninstall operation computation).
The registry resolver is rewritten to use PoolBuilder → RuleSetGenerator
→ Solver pipeline instead of pubgrub's DependencyProvider trait.

Rename mozart-constraint to mozart-semver (mirrors composer/semver) and
extract mozart-class-map-generator from mozart-autoload (mirrors
composer/class-map-generator). No logic changes.

Add new workspace crate that validates SPDX license expressions using
data from composer/spdx-licenses (git submodule). Includes build.rs
codegen from JSON, recursive descent expression parser supporting
AND/OR/WITH/LicenseRef, and integrates into mozart-core's
validate_license function.

Port composer/metadata-minifier to Rust as an independent workspace
crate. Implements expand() and minify() for Packagist's delta-encoded
version metadata. Update mozart-registry to use the new crate for
transparent minified response handling, and add __unset sentinel
support to PackagistVersion deserialization.

Replace reqwest::blocking with async reqwest across the entire codebase.
All command execute functions, registry API calls (packagist, downloader,
resolver, lockfile), and the main entry point now use async/await with
the tokio runtime. The pubgrub resolver runs on spawn_blocking since its
DependencyProvider trait is synchronous, using Handle::block_on for
async I/O within that context.

Wire up the existing --profile flag with tracing-subscriber to emit
span timings on stderr. Supports MOZART_LOG env var override and
verbose-level-aware filtering. No subscriber is installed when
--profile is off, keeping tracing macros zero-cost.

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.
