1a94cc4e - feat: lint conditional require() gated on typeof window

feat: lint conditional require() gated on typeof window Add ast-grep rules (no-typeof-window-require for .ts, -tsx for .tsx) that flag a `require()` nested in a `typeof window` ternary or `if`. This pattern bundles the server branch into the browser bundle; the fix is to split the module into a `.ts` default and a `.browser.ts` variant, which the browser bundle is now aliased to automatically (see generate-browser-variant-aliases.mjs). Existing offenders are suppressed inline with a TODO to migrate; they are out of scope for this change.
