fix(gradle): replace internal IElementType.getDebugName() with direct type equality (#254)

* fix(gradle): replace internal IElementType.getDebugName() with direct type equality

Use direct == comparison on IElementType singleton instances instead of
comparing debug name strings via the internal getDebugName() API.

Implements TC-4167

* ci: fail verifyPlugin on internal API usages

Configure pluginVerification to treat INTERNAL_API_USAGES as a build
failure, preventing future internal API regressions from passing CI.

Implements TC-4167

Assisted-by: Claude Code

* fix(gradle): guard against missing repositories block in build.gradle

Return null instead of throwing NoSuchElementException when the
repositories block is not found, preventing IDE crashes when querying
intentions for build.gradle files without a repositories block.
