refactor: commit package rename for core build files

The earlier rename commit did not persist the package-identity edits for
app.json, build.gradle, fastlane, the publish workflow, and the Kotlin
package declarations (they were reverted in the working tree after staging).
HEAD therefore still built ai.opencode.mobile. This commits the real
cc.agentlabs.opencode identity so CI builds the rebranded package.
