Subject: [PATCH] Optimize FeatureRegistryClientWithOverride.feature_path

The optimized code replaces the `.format()` method with an f-string for string formatting, achieving a **268% speedup**.

**Key optimization**: The original code uses `str.format()` with named parameters, which involves:
1. Parsing the format string to find placeholders
2. Creating keyword arguments dictionary
3. Performing multiple dictionary lookups during substitution

The f-string optimization eliminates this overhead by:
- Using compile-time string interpolation instead of runtime formatting
- Direct variable substitution without dictionary operations
- Avoiding the method call overhead of `.format()`

**Performance impact**: Line profiler shows the total execution time dropped from 5.65ms to 1.77ms. The f-string approach reduces per-hit time from ~490ns to ~335ns for the main formatting operation.

**Test case performance**: The optimization is most effective for:
- **Simple string inputs** (250-300% faster): Most common use case with typical project/location names
- **Special characters and Unicode** (150-350% faster): f-strings handle these more efficiently
- **High-frequency calls** (270%+ faster): The performance gain compounds when called repeatedly
- **Non-string types** (45-120% faster): Even with type coercion, f-strings still outperform `.format()`

This optimization is particularly valuable since `feature_path()` is likely called frequently in ML pipeline operations where path generation is a common bottleneck.
