claude@clouddev1 c7ecc64757 Matrix: create table, DDL, and app-command coverage
55 tests covering create table, drop column, drop relationship
(endpoints + by-name), add relationship, rename/change column, and
all app-lifecycle commands. The drop-column and relationship tests
drove the §2.2 writes_table fix in the previous commit.

Documents one UX wrinkle as a flagged finding: partial entry words
(`qu`) classify as DefiniteErrorAt — same as unknown commands —
because the walker only engages on a complete entry word.

859 baseline -> 989 passing; 1 ignored (pre-existing doc-test).
