Downgrade Kotlin/Ktor for Kotlin 2.1-compatible metadata

[Josh Pensky (joshpensky)]

Summary

In order to be compatible with React Native, we need to make this library compatible with Kotlin 2.1. This required downgrading the ktor dependency to 3.2.4 (which supports 2.1) and switching our build to output 2.1 metadata

This has been tested with React Native 0.79 & Expo 53 and works as expected

What Changed

• evervault-core shipped kotlin.Metadata with mv=[2,3,0] because the Ktor bump in Fix: Update Vulnerabilities #93 (to fix CVE-2025-29904) went all the way to 3.4.0, which is built with Kotlin 2.3.0.
• Pins ktor-client-core/ktor-client-okhttp to 3.2.4, which is built with Kotlin 2.1.0 metadata, while staying well past 3.1.1 (the version that fixed CVE-2025-29904).
• On top of that, the project's own Kotlin Gradle plugin was still 2.2.21, so evervault-core's own classes carried mv=[2,2,0] regardless of the Ktor pin. Downgraded the Kotlin plugin (org.jetbrains.kotlin.android, plugin.serialization, plugin.compose) to 2.1.20 and matched the pinned kotlin-stdlib-common versions, so every shipped module (evervault-core, evervault-cages, evervault-enclaves, evervault-inputs) now carries mv=[2,1,0].
• Regenerated all gradle.lockfiles to match.
• No source changes were needed — the codebase doesn't use any Kotlin 2.2-only language features.

Test plan

• testDebugUnitTest / testReleaseUnitTest — 75/75 pass for every module, against the live Evervault API
• Full assembleDebug / assembleRelease across all modules
• Verified via bytecode inspection that every shipped AAR's classes carry mv=[2,1,0] metadata (down from [2,3,0])
• Published to mavenLocal under 2.4.0-local for cross-repo consumer testing
• Confirmed no other module depends on Ktor directly (the ktorVersion var in examples/shared is unused)
