feat(experiments): expose PREFILL_MEM_FRAC + plumb --prefill-mem-fraction-static

Browse Source 
v7 with --decode-mem-fraction-static=0.8 + SGLANG_SNAPSHOT_LINK_BUF_BYTES=16GB
silently fell back to 1 GB snapshot_buf because Prefill (mem-fraction
default 0.88) left only 10.8 GB free on GPU 0. Reducing prefill
mem-fraction lets 16 GB snapshot_buf fit.
