build: type-check src against the Node 18 declarations

Browse source 
@types/node was not declared. It was installed only because mqtt's @types/readable-stream and @types/ws depend on
"@types/node": "*", and it resolved to 26.6.2, so an API newer than the "engines" floor passed the type check and
the build depended on another package's dependency list.

@types/node ^18.19.130 is now a devDependency (undici-types follows, 8.9.0 -> 5.26.5). A call to
process.loadEnvFile() (Node 20.12) in src/ now fails with TS2339. npm run check passes, the fixture compile with
skipLibCheck off included, so mqtt's declarations hold against the Node 18 types.

First run on the floor: npm test passes 24/24 on Node 18.20.8 and 20.20.2 as well as 24.21.0. No change to src/ or
dist/.
