The previous recycle logic waited for all refcounts to hit 0 before recycling, which never happened under sustained concurrent load (20+ crawls always had at least one active). New approach: - Add _browser_version to config signature — bump it to force new contexts - When threshold is hit: bump version, move old sigs to _pending_cleanup - New requests get new contexts automatically (different signature) - Old contexts drain naturally and get cleaned up when refcount hits 0 - Safety cap: max 3 pending browsers draining at once This means recycling now works under any load pattern — no blocking, no waiting for quiet moments. Old and new browsers coexist briefly during transitions. Includes 12 new tests covering version bumps, concurrent recycling, safety cap, and edge cases.
