* test(#2269): regression test for query commit --files scoping
Verify secure-phase.md, validate-phase.md, and next.md all pass --files
to their query commit calls.
* fix(#2269): add --files to three unscoped query commit call sites
secure-phase.md, validate-phase.md, and next.md were the only 3 of 65
query commit call sites that omitted --files, causing blanket staging
of .planning/ and committing unrelated files. Add --files with the
specific artifact path to each.
Closes#2269
