15.0.0: Steadier cross-origin tests on a modernized foundation

Six commands: cy.url(), cy.hash(), cy.go(), cy.reload(), cy.title(), and cy.location() now run through the automation client instead of the window object, so they hold up inside cy.origin().

Cypress 15 also moves onto a modernized foundation, Electron 36, Node.js 22, and Chromium 136; and loads TypeScript configs through tsx. It's a major version with breaking changes, so review the migration guide before you upgrade.
