Subject: [PATCH] Recognize '2.0' in compatibility inference and CLI badges
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Extends the 1.7/1.8 compatibility machinery to treat a grav >= 2.0
dependency as ['2.0']. SelfupgradeCommand's preflight already keys off
the target package's major.minor, so upgrading 1.8 → 2.0 now correctly
flags plugins that only declare 1.7 or 1.8 as blocking.

- GPM/Local/Package::inferCompatibility(): grav >= 2.0 → ['2.0']
- Installer/Install::inferCompatibleVersions(): grav >= 2.0 → ['2.0']
- IndexCommand / InfoCommand / UpdateCommand: magenta '2.0' badge

Ships as part of the final 1.8 beta so the installed base has a clean
upgrade gate when users run `bin/gpm selfupgrade` against a Grav 2.0
release. The actual migration wizard is a 2.0-only deliverable and is
NOT backported here.
