tsgo crashes with fatal error: out of memory (errno=1455) when turbo runs 30 typecheck tasks in parallel on heavily loaded Windows machines. The Go runtime allocates ~84 MB committed memory per process during startup; with 30 parallel processes the combined spike can exceed the remaining commit budget (RAM + pagefile). Add script/turbo.ts that calculates safe concurrency at runtime: concurrency = max(1, min(cpuCount, floor(freeMB / 100))) Windows-only; other platforms pass through to turbo unchanged.

100 MBper-process estimate is derived from the measured 84 MB peak, rounded up for safety margin.How did you verify your code works?
