integration: accept napi source relocation to kernel workspace

Resolves the modify/delete conflict from merging sea-napi-binding:
sea-integration had the StatementInner ValidityFlag fix in
native/sea/src/statement.rs (inherited via sea-operation merge), while
sea-napi-binding wants those files deleted because the Rust source
now lives in the kernel workspace at databricks-sql-kernel/napi/.

Resolution: propagate the StatementInner fix to the kernel napi crate
(commit a8d8df7 on krn-napi-binding), then accept the deletion here.
Built artifacts (.node, .d.ts) are repopulated by
`npm run build:native` which delegates to the kernel workspace.

native/sea/ now contains only README.md and the generated index.d.ts;
index.linux-x64-gnu.node sits next to it as a build artifact.
