chore: update all dependencies (#1209)

* chore: update all dependencies

* chore: remove lint errors

* fix(client): restore typecheck after dependency bump

vitest 4 types vi.fn() as Mock<Procedure | Constructable>, which no
longer assigns to the strictly-typed onUpdate prop; type the mock
explicitly. TS6 + the new transitive @types/node 25 stopped auto-
including node builtin module types, so import('node:buffer') failed;
add @types/node as a direct client devDependency and a scoped node
type reference in the one test that needs it.

* test: fix constructor mocks for vitest 4 Reflect.construct semantics

vitest 4 resolves new-invoked mocks via Reflect.construct, which rejects
arrow-function implementations (including mockReturnValue sugar) as
non-constructable. Convert mapbox-gl and better-sqlite3 mocks that the
code instantiates with new to regular function implementations.
