Add experimental Chicory blue-quickjs WASM runtime

[kgruszka]

Summary

• Adds optional Java 11+ quickjs-chicory module using Chicory to execute the canonical blue-quickjs wasm32 release artifact.
• Keeps the root/core Java 8 runtime unchanged and adds processor options for runtime injection.
• Implements artifact integrity checks, Host.v1 manifest/resource pinning, deterministic DV codec, source/result helpers, Host.v1 dispatcher, Chicory runtime, parity/workflow/smoke/stress tests, and validation docs.
• Splits CI validation into a Java 8 core job and a Java 17 full/Chicory job; documents the experimental module in the README.

Validation

• ./gradlew clean test -Dblue.quickjs.root=/tmp/blue-quickjs -PblueQuickJsRoot=/tmp/blue-quickjs (BUILD SUCCESSFUL in 1m 40s on latest full clean run)
• ./gradlew :clean :test -Dblue.quickjs.root=/tmp/blue-quickjs
• ./gradlew :quickjs-chicory:test -PblueQuickJsRoot=/tmp/blue-quickjs -Dblue.quickjs.root=/tmp/blue-quickjs
• ./gradlew :quickjs-chicory:test --tests '*ChicoryVsNodeParityTest' -Dblue.quickjs.root=/tmp/blue-quickjs
• ./gradlew :quickjs-chicory:test --tests '*ChicoryForbiddenSurfaceTest' --tests '*ChicoryOutOfGasTest' -Dblue.quickjs.root=/tmp/blue-quickjs
• ./gradlew :quickjs-chicory:test --tests '*ChicoryCounterSnapshotRoundTripStressTest' -Dblue.quickjs.root=/tmp/blue-quickjs
• ./gradlew :quickjs-chicory:test --tests '*LambdaPackagingSmokeTest' -PblueQuickJsRoot=/tmp/blue-quickjs
• PATH=/usr/bin:/bin ./gradlew :quickjs-chicory:test --tests '*ChicoryBlueQuickJsRuntimeSmokeTest' -PblueQuickJsRoot=/tmp/blue-quickjs
• ./gradlew :quickjs-chicory:clean :quickjs-chicory:jar -PblueQuickJsRoot=/tmp/blue-quickjs
• ./gradlew :quickjs-chicory:dependencies --configuration runtimeClasspath
• Workflow YAML parse check for .github/workflows/build.yml and .github/workflows/release.yml

Notes

• Docker is unavailable in this VM, so Lambda Java 17/21 container smoke tests are documented as environment-limited.
• The local blue-quickjs checkout is /tmp/blue-quickjs because /blue-quickjs is not writable in this container.
