Subject: [PATCH] ci(profiling): increase memory limit to prevent OOM during
 Rust compilation

The profiling tests were failing due to OOM kills (signal 9, SIGKILL)
when compiling large Rust crates like syn and regex-syntax with full
optimization (--profile profiler-release --all-features).

The combination of:
- Building on ramdisk (/mnt/ramdisk/cargo)
- Full optimization level
- Parallel compilation of many crates
- Large crates like syn (proc-macro library)

exceeded the 4GB memory limit. Increased to 6GB to provide sufficient
headroom for parallel optimized builds.
