06e1cf0a8d feat: generic _remote_attach contract for remote DuckDB extension views 
Extractors with remote tables now write a _remote_attach table into
extract.duckdb so the orchestrator can re-ATTACH external extensions
at query time. The mechanism is source-agnostic — any connector can use it.

- Keboola extractor writes _remote_attach + creates views on kbc.*
- Orchestrator reads _remote_attach, installs extension, reads token from env
- Graceful degradation: missing token → warning, local tables still work

18e5f0b6e8 feat: implement extract.duckdb contract — orchestrator + extractors 
Phase 0: extend table_registry schema (v1→v2 migration), add
source_type/bucket/source_table/query_mode columns.

Phase 1: SyncOrchestrator ATTACHes extract.duckdb files into master
analytics.duckdb. Keboola extractor uses DuckDB extension with
legacy client fallback. BigQuery extractor is remote-only via
DuckDB BQ extension (no data download).

62 tests passing.
