refactor: rename root package org.kpipe → io.github.eschizoid.kpipe

[eschizoid]

Summary

• Rename the root Java package from org.kpipe to io.github.eschizoid.kpipe across all 12 modules + examples + benchmarks so the runtime FQN matches the Maven Central group (io.github.eschizoid).
• Source moves + import rewrites only — no behavior change, no public API shape change.

What's in the diff

• 205 .java files: package + import declarations
• 37 source-root directories renamed via git mv (preserves rename history)
• 11 module-info.java exports updated
• 7 example build.gradle.kts Main-Class attributes
• OTel meter names (org.kpipe.consumer / org.kpipe.producer / org.kpipe.pipeline) and OtelTracer.DEFAULT_INSTRUMENTATION_NAME updated to match the new namespace — these are metric/tracing identifier strings, so users on the old names will see a one-time series break
• README, tracked project CLAUDE.md, javadoc code blocks
• Spotless reformat to absorb longer FQNs in README line-wrap

Deliberately not touched

• benchmarks/results/*.json — historical JMH output records the FQN that was actually executed at run time. Rewriting would falsely imply the bench was rerun under the new class name.
• com.kpipe.customer test .proto fixture — different namespace, unrelated.

Maven coordinates

Gradle group was already io.github.eschizoid (build.gradle.kts:50) — only the Java package needed to catch up. Published artifact IDs (kpipe-api, kpipe-consumer, etc.) are unchanged.

Test plan

• ./gradlew compileJava compileTestJava — clean across all modules
• ./gradlew spotlessApply && ./gradlew spotlessCheck — passes
• Unit tests pass (the one Testcontainers failure is a local Docker flake on KPipeProducerIntegrationTest — unrelated to the rename, will validate on CI)
• CI green
• Verify OTel meter names show up under the new namespace in a downstream consumer (optional smoke check)

Migration note for users

Downstream callers must update their imports from org.kpipe.* to io.github.eschizoid.kpipe.*. The artifact coordinates and class shape are unchanged — it's a sed across import statements.

Pull request overview

This PR renames the root Java namespace and JPMS module names from org.kpipe.* to io.github.eschizoid.kpipe.* so the runtime FQNs align with the Maven Central group (io.github.eschizoid). It’s primarily package/import/module rewrites plus a few identifier string updates for OpenTelemetry.

Changes:

• Renamed Java packages across modules/tests/examples/benchmarks and updated JPMS module-info.java module names + exports/requires accordingly.
• Updated documentation (README + package-info.java/module-info.java docs) and example build manifests (Main-Class) to match the new FQNs.
• Updated OTel meter / instrumentation name strings to the new namespace (io.github.eschizoid.kpipe.*).

• Doc comment formatting: the continuation line for item 2 isn’t indented, which will likely break the intended numbered-list layout in generated docs. Keep the KafkaMessageSink link aligned with the surrounding continuation lines so it renders as part of the same paragraph/list item.
  lib/kpipe-consumer/src/main/java/io/github/eschizoid/kpipe/consumer/KPipeConsumer.java:570
• This builder doc is misleading: ConsumerMetrics is an SPI (with noop()), not the type you “use … to create an instrumented instance”. The OTel-backed concrete implementation is OtelConsumerMetrics (or another ConsumerMetrics implementation).
