docs: reconcile website doc inventory with merged main scope

The merge from main added user-facing surface the pre-merge inventory had
listed as planned. Mark them documented-as-shipped: show tables /
relationships / indexes + show relationship/index <name> (V5/V5a),
help [<command>] + help types (H3), compound-primary-key foreign-key
references (T3, ADR-0043), and friendlier parse-error messaging (H1a).
Refresh the test count to 2193 and note requirements.md now uses a [/]
partial marker (trust the code, not the marker).

 table rename is intentionally absent (rename is `ALTER TABLE … RENAME TO`);
