When many projects are discovered (e.g. in a monorepo with dozens of bsconfig.json files), activating all of them in parallel via Promise.all causes severe CPU spikes as each activation involves parsing all project files and running plugins. Replace unbounded Promise.all with a concurrency-limited executor that activates at most N projects simultaneously (default 3). This spreads the activation work over time, reducing peak CPU and memory usage. The concurrency limit is configurable via the static property ProjectManager.projectActivationConcurrencyLimit.

Context
In large multi-project workspaces, all discovered projects activate simultaneously via
Promise.all, creating a CPU spike that can saturate all cores during startup. This is part 2 of 3 targeted improvements to language server performance at scale (Part of #1625).Summary
Limits the number of projects that activate concurrently during
syncProjectsto prevent CPU spikes when many projects are discovered.Promise.allwith a worker-pool pattern (default concurrency limit: 3)ProjectManager.projectActivationConcurrencyLimitTest plan
