* perf(server): bound Git process starts Git refresh bursts could keep creating short-lived processes at the concurrency ceiling, causing sustained process churn on constrained hosts. Apply one daemon-global start-rate and concurrency policy to every Git command while preserving the legacy concurrency environment variable. * build(nix): update npm dependency hash * fix(server): hold Git slots until process exit * fix(server): enforce Git limits across process lifetime * fix(server): align Git metrics with process exit * Fix Git limiter test deadlocks * Tune default Git process rate
