apply CI resource overrides to the selected nextest profile

Nextest resolves per-test overrides from the selected profile and default,
so ci_gammaloop was bypassing the reservations stored under ci. Repeat the
three existing resource/timeout policies in the selected profile, retaining
plain-ci behavior and all local profiles, test selections and numerical inputs.

Verified against the exact nextest 0.9.143 source used by CI, with independent
review, parsed-config equivalence outside those overrides, config-version
validation and diff checking. The preceding Linux run stopped after runner
shutdown; this correction does not claim a passing test run or establish OOM.

User prompt:
Yes, continue as planned, it seems like it should be ok memory wise, so just let it run until LU scalar matrix is complete, and then really finalise the ALL_GREEN PR as mentioned earlier.

Related user instruction:
Ok continue as planned now, trying to finish this damn scalar LU matrix, and only looking for improvement to the code if you can find relatively non-invasive cheap wins. The core objective is getting to ALL_GREEN commit and push merge-ready state of the corresponding PR. Then stop yourself and deem the goal achieved (if there does not seem to be any gross oversight w.r.t what is in it).
