fix: bundle @altimateai/altimate-core — required at runtime for CLI to work (#250)

altimate-core is a napi binary that must be in the compiled binary.
Marking it external causes 'Cannot find module' at runtime.

The ~35MB size increase (86→122MB per binary) is acceptable — it's
the Rust SQL engine that powers all 34 analysis methods.

dbt-integration stays external (heavy transitive deps, loaded lazily).
Database drivers stay external (installed per warehouse on demand).
