Support repo installation & test under Node.js 26.x

[MikeMcC399]

What would you like?

Support installation and test according to the CONTRIBUTING instructions under Node.js 26.x.

Why is this needed?

Attempting to install the repo with corepack yarn install fails with

better-sqlite3@npm:11.10.0 couldn't be built successfully

The engines field allows installation of the published corepack npm package also on Node.js 26.x. To provide confidence that Corepack works as intended on this release line, it should be possible to successfully run the full set of tests on Node.js 26.x

corepack/package.json

Lines 12 to 14 in 964d8cf

	"engines": {
	"node": "^20.10.0 || ^22.11.0 || >=24.0.0"
	},

Attempting an update to better-sqlite3@12.9.0 gets over the installation issue, however then the tests fail in Node.js 26.0.0, for instance with the following, although they continue to succeed in Node.js 20, 22 & 24:

   × custom registry with auth PROXY > should download yarn classic 272ms (retry x2)
     → expected { exitCode: 1, stdout: '', …(1) } to match object { exitCode: +0, …(2) }
     → expected { exitCode: 1, stdout: '', …(1) } to match object { exitCode: +0, …(2) }
     → expected { exitCode: 1, stdout: '', …(1) } to match object { exitCode: +0, …(2) }

#831 is migrating to node:sqlite, added in Node.js 22.5.0

The test error is however still occurring there.

corepack yarn build outputs the following under Node.js 26.0.0:

(node:2513) [DEP0205] DeprecationWarning: `module.register()` is deprecated. Use `module.registerHooks()` instead.
(Use `node --trace-deprecation ...` to show where the warning was created)
All shims have been generated.

This is due to tsx and I already reported this separately under privatenumber/tsx#791
