Subject: [PATCH] Optimize QdrantConfig.check_host_port_or_path

The optimized code achieves a 12% speedup by replacing tuple unpacking with individual variable assignments and simplifying the conditional logic.

**Key optimizations:**

1. **Eliminated tuple unpacking**: Changed from `host, port, path, url, api_key = (values.get("host"), ...)` to individual assignments like `host = values.get("host")`. This avoids creating a temporary tuple object and the overhead of unpacking it.

2. **Streamlined conditional logic**: Replaced the original `not path and not (host and port) and not (url and api_key)` with explicit None checks using `is None`. This reduces the number of boolean operations and makes the logic more direct.

3. **Reduced branching complexity**: The single combined condition eliminates multiple branch evaluations that would occur with the original nested boolean expressions.

**Why this is faster:**
- Tuple creation and unpacking in Python has overhead for object allocation and iteration
- Direct variable assignment is more efficient than unpacking operations
- Explicit None comparisons using `is None` are faster than relying on truthiness evaluation
- Fewer intermediate boolean operations reduce CPU cycles

**Impact on workloads:**
This optimization particularly benefits scenarios where the validator is called frequently during Qdrant configuration instantiation. Since this is a Pydantic model validator that runs during object creation, applications that create many QdrantConfig instances will see cumulative performance gains. The 12% improvement, while modest per call, can add up significantly in configuration-heavy workloads or when this validator is in initialization hot paths.
