Brings main's relationship-visualization feature (ADR-0044 in the main
namespace) and Gitea-migration cleanup onto the website branch, so the
docs can be written against the new diagram output:
- show relationship <name> / show table <T> render two-table connector
diagrams (child-FK-left, parent-right, n…1 cardinality)
- compound-FK bus routing + pairing line
- ~2000 lines across src/{app,db,event,output_render,runtime,ui}.rs,
new insta snapshots, tests/it/{show_list,compound_fk}.rs
Merged clean — no conflicts. The prior commit moved the website ADR out
of docs/adr/ into its own namespace, so main's ADR-0044
(relationship-visualization) lands with no collision.
Tests on the merged tree: 2207 passed, 0 failed, 0 skipped
(1 ignored doctest, inherited from main).
