v0.4.0
Radical simplification. incr becomes what it says on the tin: a counter you click to increment, with a dialog to set a larger number directly.
Strips the asset/price-tracking, ledger, milestone and fake-user subsystems inherited from the VWCE-share origins, then swaps React/Inertia for Blade + Livewire 4 to match ffr. Also closes the tooling gaps against ffr: PHPStan, a prebuilt CI image, and removal of stale GitHub/Jenkins CI config.
Sequencing is deliberate: delete on React first, migrate second, tighten tooling last. Porting or analysing code we intend to delete is wasted work.
Original v0.4.0 scope (price tracking) was closed as won't-fix — #38, #35 and #17 all built or fixed subsystems this milestone removes.
Target end state: one count integer, one Livewire component, one Blade view.
