fix: rebuild_source delegates to full rebuild to preserve all source views

_do_rebuild_source was creating a fresh temp DB with only one source,
then atomically replacing analytics.duckdb — wiping views from every
other source. Now it delegates to _do_rebuild so all extract dirs are
re-attached in a single pass.

Adds test_rebuild_source_preserves_other_sources to guard the regression.
