test: update tsnapi snapshot for DevframeRpcClient.close()

CI's exports.test.ts snapshots each package's public .d.ts surface; adding
close() to DevframeRpcClient/DevframeRpcClientMode is a real, intentional
API change, so devframe/client.snapshot.d.ts needs to reflect it.

Verified with a full `pnpm run build` at the repo root first, so tsnapi reads
every package's real dist output rather than erroring on a missing one — this
is the only snapshot that changed; close() doesn't ripple into any plugin's
or @devframes/hub's public surface.

`pnpm exec vitest run` — 101 files, 1087 tests, all green (was 1 failing).
`pnpm run lint` and `pnpm run typecheck` (25 packages via turbo) both clean.
