Enable Android API 23+ support by using AviatorScript interpreter mode

[Copilot]

jCasbin fails to build on Android projects with minSdk=23 because aviator 5.9.0 uses MethodHandle.invoke/invokeExact, which requires Android API 26+.

Changes

Core library:

• Configure AviatorEvaluatorInstance to use EvalMode.INTERPRETER instead of default ASM mode
• Interpreter mode avoids MethodHandle APIs while maintaining full functionality

Tests:

• Update test fixtures to use interpreter mode for consistency

Documentation:

• Add Android compatibility section noting API 23+ support

Implementation

// Before
aviatorEval = AviatorEvaluator.newInstance();

// After
aviatorEval = AviatorEvaluator.newInstance(EvalMode.INTERPRETER);

AviatorScript's interpreter mode was specifically designed for Android and non-standard JVM platforms (added in aviator 5.3.0). It executes expressions without bytecode compilation, eliminating the dependency on MethodHandle APIs.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• central.sonatype.com
  • Triggering command: /usr/bin/curl curl -s REDACTED (dns block)
• www.yuque.com
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

<issue_description>Hello,
i have Kotlin Jetpack Compose project (minSdk=23). i added jcasbin as dependency.
but on project build i got error:

Execution failed for task ':app:mergeExtDexDevDebug'.

           Increase the minSdkVersion to 26 or above.

i tried old releases of jcasbin, but without any luck.

are there possible ways to use jcasbin on API 23+?

thanks!</issue_description>
