feat!: Rename artifact to uxcam-kmp (v2.0.0)

[OneXeor]

Summary

BREAKING CHANGE: Rename Maven artifact for cleaner dependency declaration.

Breaking Change

Artifact ID changed:

• Before: dev.onexeor:uxcam-kmp-shared
• After: dev.onexeor:uxcam-kmp

Migration

Update your dependencies:

// Before
implementation("dev.onexeor:uxcam-kmp-shared:<version>")

// After  
implementation("dev.onexeor:uxcam-kmp:2.0.0")

Rationale

• Cleaner artifact name without redundant "-shared" suffix
• Follows conventions of popular KMP libraries (Ktor, Koin, Napier)
• "-kmp" suffix already indicates Kotlin Multiplatform

Test plan

• Build passes on all platforms
• Artifact publishes with new name to Maven Central
