fix(cli): make the generated v2 API a fixed point of the formatter

The pre-commit hook rewrote the generated file immediately after it was
committed, so `check:cli-api` then failed in CI reporting contract drift that
had not happened — the only difference was quote style.

The biome.json exclusion added alongside it does not help: lint-staged runs
`biome check --write` on explicit paths, which bypasses `files.includes`. It
implied protection it never provided, so it is removed.

The generator now pipes its output through `biome format --stdin-file-path`
instead, making the emitted file conformant by construction. The hook has
nothing left to change, and the check compares like with like. A formatter
failure throws rather than emitting unformatted output, since falling back
silently would reopen the same loop.
