refactor(editor): flatten flags options (#15006)

Sysix · Sysix · commit 8d8d508c29e6 · 2025-10-29T09:36:33.000Z
<img width="717" height="150" alt="grafik" src="https://github.com/user-attachments/assets/df1a4614-bf4c-464e-8aff-13bc0f42be66" /> Now the configuration `oxc.flags` is deprecated on the editor side too. It still sends the `flags` configuration to the language server, because it does not know which version is used. (defined with `oxc.path.server`). Updated all test + included a deprecated flag test.
