Subject: [PATCH] Optimize parse_query_response

The optimization replaces `dict.pop("results", None)` with a conditional check followed by `del` when the key exists. This provides a **10% speedup** by eliminating unnecessary operations in two scenarios:

**Key optimization changes:**
1. **Conditional existence check**: `if "results" in response._data_store:` only performs deletion when the key exists
2. **Direct deletion**: `del response._data_store["results"]` is faster than `pop()` when you don't need the returned value

**Why this is faster:**
- The original `pop("results", None)` always performs an internal dictionary lookup, even when the key doesn't exist, then returns the default value
- The optimized version avoids the deletion operation entirely when "results" is absent, which is more efficient than `pop()`'s internal default value handling
- `del` is inherently faster than `pop()` because it doesn't need to return a value

**Performance characteristics from tests:**
- **Best gains** (20-40% faster): When "results" key is absent (`test_basic_no_results_key`: 41.3% faster, `test_results_key_absent`: 24.4% faster)
- **Consistent gains** (5-25% faster): When "results" key exists across various data types and sizes
- **Minimal overhead**: Even with large dictionaries (1000+ keys), maintains 5-12% improvement

This optimization is particularly effective for workloads where the "results" key is frequently absent, but provides consistent benefits regardless of the key's presence.
