Add assertCompilationError assertion to testlib

[alexander-yevsyukov]

What

Adds the assertCompilationError test assertion to the Spine Compiler testlib
module, in package io.spine.testing.compiler.

The function asserts that a given action fails compilation, returning the thrown
Compilation.Error together with the console output it produced. The output is
captured via tapConsole — so a deliberately provoked compilation error does not
pollute the build log — and returned as the second component of the pair, letting
callers inspect the diagnostics.

It originates from core-jvm-compiler
(SpineEventEngine/core-jvm-compiler#101, :base test fixtures). Hosting it in
testlib lets every Compiler consumer reuse it instead of redeclaring a local
copy.

Changes

• testlib: new Assertions.kt with public fun assertCompilationError(...).
• AbstractCompilationErrorTest.assertCompilationFails now delegates to the
  new function, removing the duplicated assertThrows +
  tapConsole pattern (behavior-preserving — the abstract base is published API,
  with no in-repo subclasses).
• AssertionsSpec: covers returning the error, capturing the console output,
  and failing when no compilation error is raised.
• Version bump 2.0.0-SNAPSHOT.053 → 2.0.0-SNAPSHOT.054.

Also in this branch

A routine config submodule sync (798c1ef) and the regenerated dependency
reports matching it (c5edd7a): .gitmodules (the .agents/shared update
strategy), shared buildSrc Gradle helpers, gradle.properties, and the
pom.xml / dependencies.md reports (transitive bumps such as spine-base
411→413, spine-server 375→376, core-jvm-plugins 073→077, prototap
0.15→0.16). These are config-distributed / generated files kept in sync and are
independent of the testlib change.

Follow-up

Once the Compiler is released with this function, core-jvm-compiler should
migrate to it and drop its local copy. Tracked in
SpineEventEngine/core-jvm-compiler#102.

Pull request overview

This PR adds a reusable assertCompilationError assertion to the testlib module (io.spine.testing.compiler) so compiler consumers can assert compilation failures while capturing (and suppressing) console diagnostics.

Changes:

• Introduces assertCompilationError(action) returning (Compilation.Error, consoleOutput) captured via tapConsole.
• Refactors AbstractCompilationErrorTest.assertCompilationFails to delegate to the new assertion (removing duplicated assertThrows + tapConsole logic).
• Adds AssertionsSpec covering returned error, captured output, and the failure mode when no compilation error is thrown.
