build(deps-dev): upgrade TypeScript to 6 (#153)

TypeScript ^6.0.3 and @types/node ^26.6.6. tsconfig drops `baseUrl`
(deprecated in TS 6; `paths` are relative to the tsconfig).

TS 6's lib accepts only ArrayBuffer-backed data where WebCrypto, pkijs
and x509 take a `BufferSource`. Values that are ArrayBuffer-backed now
say so in their types:

- `PDFStream`, `PDFObject`, `PDFDocument`, `PDFDocumentUpdate` and
  `JPEG` declare their views as `Uint8Array`, as the 1.x declarations
  did, instead of TS 6's inferred `Uint8Array<ArrayBuffer>`;
- `PDFTextString.toUint8Array()`, `PDFHexString.data` and
  `ViewWriter.toUint8Array()` return `Uint8Array<ArrayBuffer>`;
- the signing callback receives `Uint8Array<ArrayBuffer>`, so it can be
  passed to `crypto.subtle.digest` directly.

pdf's own signatures take @peculiar/utils' `BufferSource` throughout.
Where such a value goes to WebCrypto, pkijs or x509, the encryption
code uses a view of the same memory (copying only a SharedArrayBuffer)
and pdf-doc converts it with `toArrayBuffer`.
