fix: resolve @surrealdb/spectron from source in tests

Map @surrealdb/spectron to ./packages/spectron/src in the root tsconfig
paths, matching the existing convention for surrealdb and @surrealdb/sqon.
Without this mapping the package only resolved via its built dist/ bundle,
so spectron tests failed with "Cannot find module '@surrealdb/spectron'"
whenever the package had not been built.
