fix(glx-runtime): deps belong beside the version entries, not inside one

CI: `E_INTERNAL: [glx-runtime] failed:` with an empty message, twice. The
`deps = { runtime = { "xim:graphics" } }` had been placed inside the
2026.08.08 version entry. The descriptor parsed, the graphics stack was never
installed, the subos therefore had no libGL.so.1, and the install failed on
the required-library check -- reporting the library rather than the misplaced
key, which is why the message looked like a missing package instead of a
typo.

Every other recipe in both indexes puts deps at platform level. Moving it
there means the legacy 2026.06.03 entry declares it too and pays for a
download it does not read; the alternative is deleting a published version,
which breaks anyone pinned to it outright.
