Add prefixes to SPARQL queries and prettify example Turtle output.
...
Add namespace prefixes (rdfs, migrants, person, personp, work, workp,
location, locationp) to query files. Use --prettify in Rake tasks so
example files use abbreviated IRIs. Fix 2hop task to use graph-02.

Add Step 2: SPARQL UPDATE queries to transform literals into objects.
...
19 queries in updates/ convert categorical columns (continent, country,
city, gender, profession, etc.) from literals to typed RDF objects with
rdfs:label. map/step-02.rb applies them to produce data/graph-02.ttl.
Also fix step-01.rb to sanitize column names with spaces and avoid
prefix serialization issues with fragment IRIs.
