🚀 nitro v3

[pi0]

[!NOTE] This PR is not to merge but you can overview undergoing major nitro v2...v3 breaking changes which will be mostly breaking changes and removals in the first step.

[!NOTE] We will keep backporting fixes as much as possible to the nitro v2 until the community adoption of nitro v3. For non-breaking change improvements, please base PR branches on v2 branch. For proposing breaking changes, you can use main. Most of the upcoming features will land to v2 as well ~> v2.10.0 release tracker

⌛ ETA: Within June with the collaboration of the Nuxt team to sync releases
