This PR bumps Gradle to 9.8.2, rolls Kotlin back under the Kotlin version cap, and moves the .agents/shared pin to the agents tip, which brings in the new kotlin-version-cap skill.

Changes

• Gradle 9.8.1 → 9.8.2 (5af55497). Gradle 9.8.2 still embeds Kotlin 2.4.10, per the compatibility matrix and ./gradlew --version. The cap stays at 2.4.10.
• Roll Kotlin back to 2.4.10 (32aca21a). The SDK's Kotlin must not exceed the Kotlin embedded in the Gradle version of config's wrapper, because our Gradle plugins and the Spine Compiler run on Gradle's embedded Kotlin. Gradle pins that Kotlin with strictly constraints on buildscript classpaths. Kotlin 2.4.21 was raised in d655c277 and has been making Spine Compiler builds unresolvable in consumers.
  • Kotlin 2.4.21 → 2.4.10: Kotlin.runtimeVersion, Kotlin.embeddedVersion, and kotlinEmbeddedVersion in buildSrc/build.gradle.kts.
  • KotlinPoet 2.4.0 → 2.3.0. 2.4.0 requires Kotlin 2.4.20; 2.3.0 requires 2.3.20.
  • KotlinCompileTesting (kctfork) 0.14.0 → 0.13.0. 0.14.0 requires Kotlin 2.4.20; 0.13.0 requires 2.4.0.
• .agents/shared f3d8ac5 → 9cb20bd (780b333a). This adds the kotlin-version-cap skill and its kotlin_cap.py script, which bump-gradle, dependency-update, and dependency-audit now use. It also brings cross-repo gating in pre-pr-gate.sh and worktree-aware hook scripts. Every hook script wired in .claude/settings.json and .codex/hooks.json still exists and is executable at 9cb20bd. None of the commits in the range asks consumers for follow-up changes.
  The submodule's content is not part of this PR's diff. Review it in the agents compare view for f3d8ac5...9cb20bd (61 commits, 33 files), where each change was reviewed in its own agents PR (Stamp copyright headers in .html files agents#44 through Cap the SDK's Kotlin at the version embedded in Gradle agents#50).

Follow-up: rebuild artifacts built with Kotlin 2.4.21

These local/ pins were published with Kotlin 2.4.21, and they keep that requirement until they are rebuilt (kotlin_cap.py requirement --cap 2.4.10):

Artifact	Pinned version	Kotlin requirement
io.spine:spine-base	2.0.0-SNAPSHOT.461	2.4.21
io.spine:spine-reflect	2.0.0-SNAPSHOT.202	2.4.21
io.spine.tools:base-testlib	2.0.0-SNAPSHOT.215	2.4.21
io.spine:spine-logging	2.0.0-SNAPSHOT.426	2.4.21
io.spine.tools:* (tool-base)	2.0.0-SNAPSHOT.426	2.4.21
io.spine.tools:prototap-*	0.17.3	2.4.21

After this merges, those repositories need a rebuild in dependency order (base-libraries → … → compiler → core-jvm-compiler) with this config. Their local/ pins can then move to the rebuilt versions. Every other local/ pin is within the cap.

Verification

• ./gradlew :buildSrc:build detekt --rerun-tasks on Gradle 9.8.2 with Kotlin 2.4.10: 224 tests pass, and validatePlugins and detekt are clean.
• kotlin_cap.py: the changed modules and kotlin-bom (checked with --platform) are all within the 2.4.10 cap.
• /pre-pr passed: dependency-audit, spine-code-review, and kotlin-engineer all approve. The version gate does not apply, since config has no version.gradle.kts.

🔵 Needs a closer look

The described shared-agent hook and gating changes were absent from the supplied diff and still require human review.
