Rung 6 of the #376 ratchet: `"lineEndings": "lf"` is enabled and promoted to
"error". Its 37 findings are cleared and nothing but line endings changed.
- 34 files ended without a newline; each now ends with exactly one LF.
- 3 files were stored with CRLF (services/public/getgroups.sas and the two
sas9 lineage services, getmetacols and getmetatables), against the repo's
own `* text=auto eol=lf` in .gitattributes. They are converted to LF.
Checked mechanically that this is whitespace only: for every changed file,
HEAD's content and the new content are identical once CRLF is folded to LF
and the trailing newline is stripped.
VERIFICATION
- `npm run lint:sas`: 0 warnings, 0 errors, exit 0.
- `sasjs compile`: succeeds.
- On sas.4gl.io, against a scratch appLoc seeded with makedata:
"Tests that pass: 64/64 (100%)".
