ci: re-trigger sweep after srt-slurm fork rebase

Previous Run Sweep failed because SemiAnalysisAI/srt-slurm@feat/inferencex-perfmon
was based on PR #35's head from 2026-04-13, predating the default_bash_preamble
schema field that the launcher writes into srtslurm.yaml. srtctl rejected the
config with 'Unknown field' and the job never submitted.

Fork branch has now been rebased onto current NVIDIA/srt-slurm main (which
has default_bash_preamble), with PR #35 perfmon commits + Aryan's role-label
follow-up squashed/cherry-picked on top. Empty commit here re-fires the
Run Sweep workflow so we can validate end-to-end on real DSv4 FP4 GB300.
