Scrub references to other projects (fizzpop, claude-code, openclaw)

Replace personal/project identifiers with neutral examples:
- dev.fizzpop.arcp -> dev.arcp (Java/Kotlin packages)
- github.com/fizzpop/arcp{,-go} -> github.com/agentruntimecontrolprotocol/{kotlin-sdk,go-sdk}
- 'claude-code' -> 'example-client'; 'openclaw' -> 'example-runtime'
- 'telegram:nick' -> 'chat:operator'; 'nick@*' -> 'alice@example.com'
