refactor(update): Slice A — align update.rs with Composer's UpdateCommand pipeline

- Rename ChangeKind::Remove → Uninstall, drop Unchanged variant (propagate
  to remove.rs / require.rs); mirrors Composer's UninstallOperation naming
- Fix magic-keyword mirrors detection: use Composer's count-diff semantic
  (any keyword triggers mirrors mode) instead of all-are-magic; mutex check
  now fires correctly for mixed lists like `update foo lock`
- Add --patch-only pre-solve lock-presence check (previously missing;
  Composer throws InvalidArgumentException when no lock exists)
- Add --patch-only pre-solve constraint injection: inject >=M.N.P.0,<M.(N+1).0.0
  into temporary_constraints before the resolver runs, mirroring
  UpdateCommand::execute 177-195
- Delegate --bump-after-update to bump::do_bump (mirrors Composer's
  BumpCommand::doBump delegate); add \!--lock guard per Composer 280-282
- Drop parse_minimum_stability wrapper; call package::Stability::parse directly
- Replace is_platform_dep with is_platform_package from mozart_core::platform
  (the local variant was incomplete: missed hhvm and composer pseudo-packages)
- Wrap "Lock file operations" and "Writing lock file" in <info> tags
- Update --no-suggest deprecation wording to match Composer 3 message
