This enables Kotlin in the default USE_LSP=true fixture path, adds Kotlin LSP/non-LSP mode-specific fixture assertions, and keeps unsupported languages from spawning empty analyzer commands.

Validation:

• git diff --check
• cargo test -p lsp language::tests:: -- --nocapture --test-threads=1
• cargo test -p ast testing::test_kotlin -- --nocapture --test-threads=1
• PATH=/tmp/stakgraph-kls/server/bin:$PATH USE_LSP=true cargo test -p ast testing::test_kotlin -- --nocapture --test-threads=1
• cargo test -p ast --lib -- --test-threads=1
• PATH=/tmp/stakgraph-kls/server/bin:$PATH USE_LSP=true cargo test -p ast --lib -- --test-threads=1
