fix(resolver): apply root "X as Y" aliases via pool second pass

Mirrors Composer's `RootPackageLoader::extractAliases` +
`PoolBuilder::loadPackage` flow: strip the `as` clause from each root
require so the SAT side sees only the LEFT-hand constraint, and after
every package is loaded run a second pass that materializes an alias
entry for any input matching `(name, version_normalized)`. Locked-only
packages in a partial update are excluded via a new
`ResolveRequest::locked_package_names` so they don't pick up the alias
(`propagateUpdate=false` in Composer).

Two adjacent fixes uncovered while making `install_aliased_alias`
green:
- `Version::cmp` treated unnamed wildcard branches (`1.0.x-dev`,
  `is_dev_branch=true && name=None`) as below every numeric version.
  They are semantically the same as the four-segment `*-dev` form
  Composer's `normalizeBranch` emits, so let only *named* branches
  take the shortcut.
- `Constraint::Exact` / `NotEqual` used the derived `==`, which
  compared `is_dev_branch` field-by-field and missed the
  wildcard/numeric equivalence. Switch to `cmp` so both forms count
  as equal.
- `Pool::matches_package` now falls back to parsing `pretty_version`
  when the `version` parse doesn't match the constraint, so a
  `dev-master` query lines up with a pool entry stored as the
  internal `9999999.x.x.x-dev` expansion.

Net effect on installer fixtures: `install_aliased_alias` newly
green, plus `aliased_priority`, `aliased_priority_conflicting`, and
`install_dev_using_dist` come along for the ride.
