Nuxt 4.x Compatibility Issue: @wagmi/vue Disabled Due to Version Check (^3.0.0 Required)

[lvbaiying]

Description
Currently, @wagmi/vue is disabled in Nuxt 4.x projects due to a version check that only allows ^3.0.0. This prevents developers from using the library after upgrading to Nuxt 4, even though Nuxt 4 is mostly backward-compatible with Nuxt 3.

 WARN  Module @wagmi/vue is disabled due to incompatibility issues:
 - [nuxt] Nuxt version ^3.0.0 is required but currently using 4.0.3

Proposed Solution
• Relax the Nuxt version constraint from ^3.0.0 to >=3.0.0 <5.0.0, or
• Explicitly add Nuxt 4.x support in the module’s meta configuration.
• If full testing for Nuxt 4.x is not yet complete, consider providing an experimental opt-in flag so that developers can test and provide feedback.

Benefits
• Allows early adopters of Nuxt 4 to continue using @wagmi/vue without forking.
• Helps gather real-world compatibility feedback from the community.

Additional Context
Nuxt 4 builds upon Nuxt 3 and maintains API compatibility for most modules. In local tests, @wagmi/vue appears to work with Nuxt 4.x when bypassing the version check.
