⬆️ Upgrade dependencies

@types/node to ^26.6.1 and cspell to ^10.3.2 — the only packages
check-outdated found behind the registry, both bumps within the existing
semver ranges. cspell 10.3.2 drops its transitive
fast-json-stable-stringify. npm run verify is green with no rule or
format fallout. maintain:outdated still flags @types/node as "reverted"
because DefinitelyTyped's latest dist-tag stays on the 22.x LTS series;
known false positive, advisory scan only.
