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).
Brings website up to date with main (18 commits): H1a parse-error
pedagogy, V5/H3/V5a show+help commands, ADR-0043 compound-PK FK,
handoffs 58-59, and the GitHub->Gitea doc scrub (Cargo.toml repository,
CLAUDE.md, ADR-0001 amendment, requirements).
Conflict: docs/adr/README.md. main and website had each created an
ADR-0042 (main: H1a parse-error pedagogy; website: public website &
docs site). Renumbered the website ADR to 0044 (next free after main's
0042/0043) and updated all references (ADR file, plan file, STYLE.md,
astro.config.mjs, README index). Website build verified green.
