Reformats the entire Craftimizer source tree with dotnet csharpier 1.2.6
to match the Hellion Forge house style (matches what HellionChat enforces
in its pre-push pipeline). Pure whitespace + using-block sorting; no
semantic changes.
This is a one-time noisy commit. Future code edits in this fork should
land csharpier-clean because the pre-push hook (introduced in the next
commit) runs `dotnet csharpier check Craftimizer/` as Block C of the
preflight gate.
Trade-off acknowledged: this widens the merge gap with upstream
Craftimizer should Asriel ever resume maintenance. Given the upstream
has been dormant since FFXIV 7.4 and the fork is light-rename only
(internal namespaces unchanged), the marginal cost is acceptable.
