test(p10-2): integration smoke tests for Tier 2 (k8s yaml + Dockerfile + Cargo.toml)

Three new tests in code_ingest_smoke.rs verifying isolated-TempDir ingest +
--code-lang filter + Citation::Code.lang / .symbol shape for each Tier 2
chunker. Brings the suite to 12 tests (Rust 3 + Python 1 + TS 1 + JS 1 +
Go 1 + Java 1 + Kotlin 1 + yaml 1 + dockerfile 1 + manifest 1).
