utf-8 is the default for source files but can be overwritten via options

Rename `putstring` instruction as `dupstring`

2026-04-29T21:30:50+00:00

As well as `putchilledstring` as `dupchilledstring`.

This is more consistent with similar `duparray` and `duphash`
instructions and better reflect it's behavior.

[ruby/prism] Generate templated sources under main/java-templates

2026-04-01T14:03:45+00:00

This path avoids the sources getting wiped out during `mvn clean`,
since they are not generated during the maven build.

This patch also moves the generated WASM build under src/main/wasm
since it is really a source file and not a test file. It will not
be included in the built artifact.
