chore: require Node.js >= 20.19 (rou3 v1)

[pi0x]

rou3 v1 (updated in 6d59f61, released in v2.0.1-rc.33) declares "engines": { "node": ">=20.19.0" }, so h3's own >=20.11.1 no longer reflects what actually runs.

• package.json: engines.node → >=20.19.0
• MIGRATION.md: Node.js requirement → >= 20.19
