v1.2.9

Release notes

This patch release doesn't bring any new feature nor fix. It is just a "courtesy-release" to enable from now on, publishments via the newly introduced npm provenance statements.

I also took the chance to improve a bit the (one year old) codebase by:

• Use defineOptions in the setup block
• Refactor reactivity-related syntax to improve readability using setters
• Enable watch mode for both dev and GUI testing
• Drop the buggy and unstable Cypress webkit testing (support still experimental)
• Update all dependencies
