…austion (sourcebot-dev#590) When syncing generic-git-host connections with thousands of repositories, unbounded Promise.all caused resource exhaustion (EAGAIN errors) by spawning too many concurrent git processes. This resulted in valid repositories being incorrectly skipped during sync. - Add p-limit to control concurrent git operations (max 100) - Follow existing pattern from github.ts for consistency - Prevents file descriptor and process limit exhaustion - Uses rolling concurrency to avoid head-of-line blocking Fixes sourcebot-dev#590
