fix(idris): // -> -- on Owner header line (restores idris2 --build)

Line 2 of 8 Idris ABI/formal files (.ipkg + .idr) was `// Owner: ...` — `//`
is not an Idris comment (Idris uses `--`), so `idris2 --build` died at
tokenisation ("Can't recognise token") on both ephapax-abi.ipkg and
ephapax-formal.ipkg. Delimiter-only change (`//` -> `--`); owner string and
the line-1 `|||` SPDX doc-comment unchanged. Both ipkgs now build (exit 0):
Region/Qualifier/RegionLinear and Types/Invariants/Foreign.
