chore(deps): update dependencies and fix TS 5.9 type error

Update @scure/base 1.2.4→1.2.6, typescript 5.3→5.9.3, vitest 1.1→1.6.1,
prettier 3.1→3.8.1.

Fix TS 5.9 strict Uint8Array/ArrayBuffer typing in stringToBuffer —
return .buffer from TextEncoder.encode() to satisfy ArrayBuffer return type.

Bump version to 0.1.1.
