Retire McJava dependency object and purge ProtoData/McJava from consumer buildSrc

[alexander-yevsyukov]

Summary

Retires the McJava dependency object (the mc-java plugin, io.spine.mc-java) from buildSrc, in parallel with the earlier ProtoData retirement, and teaches migrate to purge both retired objects from consumer repositories. Also refreshes the local/ dependency versions.

McJava is superseded by CoreJvm Compiler (io.spine.core-jvm, the CoreJvmCompiler object), just as ProtoData was superseded by Spine Compiler.

Changes

Retire McJava

• Delete buildSrc/src/main/kotlin/io/spine/dependency/local/McJava.kt.
• Remove the mcJava shortcut and the McJava import from BuildExtensions.kt, and rewrite the spineCompiler KDoc that linked [mcJava] (would otherwise break the Dokka publish check).
• Drop the two McJava entries from scripts/buildSrc-migration.kts.

migrate consumer cleanup

• Add rm -f for ProtoData.kt and McJava.kt under buildSrc/.../dependency/local/, after cp -R buildSrc ... cp -R overlays sources but never deletes files dropped from config, so consumers that received these objects keep stale copies that no longer compile. ProtoData was removed earlier in 45095663, but its consumer cleanup was missed — this fixes both.

Refresh local/ versions

Docs

• Add team-memory note core-jvm-compiler-replaces-mc-java.md recording the succession.

Reviewer notes

• ./gradlew :buildSrc:test detekt passes; ./gradlew -p buildSrc compileKotlin clean; no remaining [mcJava]/McJava references.
• Reviewed with spine-code-review, dependency-audit, kotlin-engineer, review-docs — no blockers.
• Version gate N/A: config has no root version.gradle.kts.
• Paired constants (Base version/versionForBuildScript, Compiler fallbackVersion/fallbackDfVersion, CoreJvmCompiler version/dogfoodingVersion) moved together to preserve the existing invariant — this includes the dogfooding/build-script versions used to build config itself.
• Suggest squash-merge: the two Remember McJava commits are redundant.

Use a published ProtoTap plugin version

For consumers that use the prototap plugins-DSL shortcut in BuildExtensions.kt, this version is emitted as id("io.spine.prototap") version "0.15.0", but the official Gradle Plugin Portal still lists 0.14.0 as the latest published version and its marker dependency example also uses 0.14.0 (https://plugins.gradle.org/plugin/io.spine.prototap). Those builds will fail during plugin resolution until 0.15.0 is actually published there, so keep this at a resolvable version or avoid wiring the plugins-DSL accessor to an unpublished release.

Pull request overview

This PR removes the retired McJava dependency object from config’s shared buildSrc, updates migration tooling so consumer repositories don’t keep stale copies after ./config/pull, refreshes several local/ dependency versions, and records the McJava → CoreJvmCompiler succession in team memory.

Changes:

• Retire McJava from buildSrc (delete the object, remove related accessors/imports, and drop migration script entries).
• Update migrate to delete stale ProtoData.kt and McJava.kt from consumer repos after copying buildSrc.
• Bump versions for several io.spine.dependency.local.* entries and add a project memory note documenting the replacement.
