Make turbopack-cli persist filesystem build cache to avoid cold builds

Make turbopack-cli persist filesystem build cache to avoid cold builds targets a $1.5B = 250K engineering orgs × $6K ACV total addressable market with medium saturation and a year-over-year growth rate of 12% YoY based on developer tools and CI/CD tooling growth (sources: GitHub Octoverse, Stack Overflow trends and commercial CI reports).

Key trends driving demand: Monorepos and multi-package workspaces are increasingly common, driving demand for aggressive incremental builds because full builds are prohibitively slow.; Cloud CI cost sensitivity is rising, making caching a direct cost-saving lever that finance and engineering leadership can quantify.; Ecosystem shift to Rust and high-performance build tooling (like Turbopack) creates openings for native tooling that matches the runtime language and performance expectations.; Developer experience investment is becoming a competitive advantage; faster iterative loops translate to better feature throughput and retention..
