Run against TirSystem-BashScript/RepoFoundry (39 shell files): shellcheck
passes with the project's .shellcheckrc, shfmt fails on 10 files only
because of the case indentation and passes after one .editorconfig line;
the pull request itself passes. Record the findings for the guide, review
the change (RC-039) and update TM-001. The adoption is complete when
RepoFoundry PR 76 is merged.
