Read `config.audit.block-abandoned` from composer.json (defaults to
false) and propagate it to the resolver. When set, the pool builder
skips packages whose `abandoned` field is truthy (`true` or a non-empty
replacement string), matching `SecurityAdvisoryPoolFilter`'s behavior in
`Composer\DependencyResolver`. With no candidates left, a root require
that only matches abandoned versions fails resolution with exit 2.

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.

Composer's ArrayLoader and AliasPackage rewrite "self.version" to the
declaring package's own version when building Link objects, so a
package's replace/provide/conflict/require constraints carry a concrete
"= <version>" rather than the literal string. Mozart was passing
"self.version" through verbatim, which then failed to parse in
Pool::matches_package and caused replace_alias.test to fail to find a
provider for c/c 1.* via a/a's branch alias.
Push the substitution into make_pool_links, threading the source
package's normalized version through the call sites in resolver.rs
(packagist/inline/composer-repo) and vcs_bridge.rs.

Adds the missing pieces for installer fixtures that pin a dev package
via `dev-foo#hex` or rely on Composer's `default-branch: true` synthetic
`9999999-dev` alias.
Mirrors Composer at four layers:
1. `mozart_semver::parse_single` strips `dev-...#hex` / `....x-dev#hex`
suffixes from constraints (Composer's `parseConstraint` regex).
2. `PackagistVersion` carries `default_branch`. When set on a `dev-`
package with no numeric prefix, `packagist_to_pool_inputs` emits
the synthetic `9999999-dev` alias — but skips it when an explicit
`extra.branch-alias` already covers the version (matches
`ArrayLoader::getBranchAlias`).
3. `RuleSetGenerator::generate` picks up `addRulesForRootAliases`:
any pool alias whose target was added gets its own alias↔target
rules so the SAT solver pulls them in together.
4. `lockfile::generate_lock_file` extracts root `#hex` overrides from
`require`/`require-dev` and rewrites source/dist references (and
github/gitlab/bitbucket archive URLs) on the matched package, the
`setSourceDistReferences` ladder Composer runs in `PoolBuilder`.
Resolver also infers `Stability::Dev` from a `dev-foo` style
single-atom constraint when no explicit `@flag` is given, mirroring
the second loop of `RootPackageLoader::extractStabilityFlags` so the
package isn't filtered out under default `stable` minimum-stability.
Newly green: install_branch_alias_composer_repo, install_reference,
conflict_with_alias_prevents_update_if_not_required,
unbounded_conflict_matches_default_branch.

Plumb Composer's `extra.branch-alias` mechanism end-to-end so a dev
branch (e.g. `dev-foobar`) can be installed alongside its numeric alias
(e.g. `3.2.x-dev`) and resolve constraints written against the alias
target.
Concretely:
- `mozart-semver`: stop treating pure-numeric `-dev` as a wildcard
branch — `3.2.9999999.9999999-dev` (the form `normalizeBranch` emits)
now parses as a classical version with `is_dev_branch=false`, so
constraints like `3.2.*` match it.
- `mozart-registry/composer_repo`: load `type: composer` repositories
from `file://` URLs (legacy embedded `packages.json`).
- `mozart-registry/resolver`: emit pool entries in pairs for dev
branches with `extra.branch-alias`, link them via `is_alias_of`, and
apply `@dev`/`@beta` etc. stability suffix flags from root requires.
- `mozart-sat-resolver`: alias rules (`PackageAlias` /
`PackageInverseAlias`) so alias and target install together; alias
packages skipped from same-name conflict indexing.
- `mozart-sat-resolver/policy`: `DefaultPolicy` now honors
`prefer_stable` via Composer's stability-tier comparison.
- `mozart-registry/lockfile`: split resolved set into real packages vs.
alias entries; populate the `aliases[]` block.
- `mozart-registry/installer_executor`: new `MarkAliasInstalled`
operation; `format_full_pretty_version` mirroring
`BasePackage::getFullPrettyVersion` (appends source ref[0..7] for
dev/git packages).
- Test harness rewrites fixture-relative `file://` URLs to absolute
paths.
Newly green fixtures: `install_branch_alias_composer_repo`,
`alias_solver_problems`, `alias_solver_problems2`,
`conflict_with_all_dependencies_option_dont_recommend_to_use_it`,
`unbounded_conflict_does_not_match_default_branch_with_branch_alias`,
`unbounded_conflict_does_not_match_default_branch_with_numeric_branch`.

Composer's PackageRepository lets composer.json embed full package
metadata under repositories[].package, mirroring the on-disk
Packagist response shape. The vast majority of installer fixtures
under composer/tests/Composer/Test/Fixtures/installer (179 of 189)
rely on this — they declare every package they need inline rather
than hitting the network.
Three pieces wire this into Mozart:
1. mozart-core::package::RawRepository: relax `url` to Option<String>
(Composer enforces presence per repo type, not at JSON parse) and
add `package: Option<Value>` to receive the inline definition,
which can be a single object or an array.
2. mozart-registry::inline_package: a new module that walks
`&[RawRepository]`, picks out type=package entries, and reshapes
each `package` payload into a PackagistVersion (auto-computing
version_normalized when omitted, matching Packagist's output).
3. resolver::resolve and lockfile::generate_lock_file: feed inline
packages into the SAT pool builder and short-circuit the Packagist
fetch when generating the lock entry for a resolved inline package.
The package-name set is shared with the existing VCS-skip logic so
the seed and transitive loops don't double-fetch.
One additional install-time change: in install_from_lock, packages
that have neither dist nor source are now skipped silently instead
of bailing with "no dist or source information". This mirrors
Composer's MetapackageInstaller (no installer for type=metapackage)
and is also what Composer's own AllFunctionalTest exercises via
InstallationManagerMock — most inline-package fixtures define
synthetic packages with no download metadata, expecting the install
operation to be recorded but not actually run.
Net effect: installer fixture scoreboard jumps from 7/187 to 103/187.
The 84 fixtures still ignored hit issues unrelated to inline-package
plumbing — aliases, replace/provide chains, dev-reference handling,
allow-list updates, etc. — and are tracked separately.

Replace manual tokio::runtime::Handle::current().block_on() calls with
native async/await throughout all VCS drivers. Introduce AnyVcsDriver
enum for static dispatch to avoid dyn trait with async methods.

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.
