Hold TypeScript at 5.9 so npm ci keeps resolving

[vpetersson-bot]

Every job on the monthly npm bump fails at npm ci:

npm error ERESOLVE could not resolve
npm error While resolving: typescript-eslint@8.70.1
npm error Found: typescript@7.0.2
npm error peer typescript@">=4.8.4 <6.1.0" from typescript-eslint@8.70.1

typescript-eslint caps its typescript peer at <6.1.0, and its latest release
still does — TypeScript 7 removed ts.Extension.Cjs, which
@typescript-eslint/typescript-estree reads at load time. Until typescript-eslint
ships TypeScript 7 support there is no version of this repo that can take the bump.

This takes the rest of the bump (@sentry/browser 11, jsdom 30, vitest 5,
globals 17, @types/node 26) and leaves typescript on ^5.9.3, plus a
dependabot ignore entry so TypeScript 7 is not proposed again. Drop the ignore
entry once typescript-eslint supports it.

Verified on Node 24: npm run lint, npm run format:check, npm run type-check,
npm run build and npm test (22 files, 204 tests) all pass.
