📐 fix: correct what the adversarial review of the page found

Five auditors read the finished page against the source; a second pass
tried to refute each finding. What survived:

**The esbuild row was wrong, and dangerously so.** It said esbuild takes
"the same settings via tsconfigRaw" as tsc. It does not: esbuild lowers
standard decorators only when its own *top-level* `target` is below
`esnext`. A `target` inside `tsconfigRaw` sets the
`useDefineForClassFields` default and nothing else. I ran it — the
decorator survives verbatim and the module throws SyntaxError on import,
which is the exact silent passthrough the section blames on oxc. The
repo's own vite plugin and toolchain test always passed `target`
top-level, so the executed matrix never backed the advice the docs gave.
Both halves are now asserted in src/toolchain.test.ts.

**"This table is executed by a test" did not cover the oxc row** — the
only ✗, and the row the whole section is built around. It cannot be:
oxc ships as a native binary with no standalone transform API, which the
test file already said in a comment. Fixed on the page and in the README.

Reference corrections, each verified against the source:
- fromRequest has no …Sync twin; the group blurb claimed every entry did
- @IsNotIn does not narrow its field, unlike its five neighbours
- @MinDate/@MaxDate take a Date as well as a thunk
- @Validate has three parameters, not two; defineRule has four
- getConfig() and resetConfig() were missing from a group rendered under
  the heading "Everything cereale exports"

And on the page itself: the vite.config.ts snippet never imported
defineConfig, so pasting it failed; and the plugin note omitted that
.tsx is excluded by default, which would drop a reader straight back
into the 0-test hole the section exists to describe.
