v0.4.0

Feat

• lineage context scoped to selection roots
• stg_orders as a real dbml table in the example (demos intra-dbml lineage and source phantoms)
• phantom upstream nodes; realistic example lineage
• paired-file convention name.dbml + name.manifest.json
• fact-to-fact lineage in the example manifest (no FK counterparts)
• stage demo databases for dev via the same script as deploy

Fix

• legible lineage edges (stronger dashes, arrowheads) + example-files regression test
• example lineage models a clean layered warehouse (no intra-dbml deps)
• lineage is a table-level dotted overlay; dbml refs stay primary
