Pins .nvmrc to Node.js v24.22.1 instead of lts/*.

Why

lts/* now resolves to Node 26 (26.13.0 became LTS on 2026-10-28). The Check workflows job does not set a Node version, so it follows .nvmrc, and on Node 26 its yarn --immutable step fails (3 retries), which also fails All jobs pass:

node_modules/yargs/yargs:3
const {applyExtends, cjsPlatformShim, Parser, Yargs, processArgv} = require('./build/index.cjs')
ReferenceError: require is not defined in ES module scope, you can use import instead
Node.js v26.13.0

The allow-scripts install plugin runs @lavamoat/allow-scripts (3.4.2), which does require('yargs/yargs'). In yargs 17.7.2 (locked) that is an extension-less file in a "type": "module" package, which Node 26 no longer loads with require.

Run	Node	Check workflows
main @ e4ce5ed (Oct 29)	24.22.1	pass
main @ cc6a9cf, 0.13.0 release (Nov 2)	26.13.0	fail

Same change as MetaMask/device-mcp#53. Reproduced there: node node_modules/@lavamoat/allow-scripts/src/cli.js --help works on 24.22.1 and throws the same error on 26.13.0.

The build, lint and test jobs set their own matrix (20.x / 22.x / 24.x) and are not affected. engines stays ^20 || ^22 || >=24.

Follow-up (not in this PR)

Node 26 support for the install tooling: yargs 17.7.3 points yargs/yargs to a .cjs file and loads on Node 26 (checked locally), so yarn up -R yargs (or @lavamoat/allow-scripts 5.x) would let .nvmrc move to Node 26 later.
