Function normalize_model_name 

pub fn normalize_model_name(name: &str) -> String

Normalizes model names by removing provider prefixes and version suffixes.

Removes patterns like:

• Provider prefixes: bedrock/, openai/.
• Date suffixes: -20231201, -12345678 (exactly 8 ASCII digits).
• Version suffixes: -v1.0, -v2.

Optimized to minimize string allocations (a single allocation at the end).

Examples

use vct_core::pricing::normalize_model_name;

assert_eq!(normalize_model_name("claude-3-sonnet-20240229"), "claude-3-sonnet");
assert_eq!(normalize_model_name("gpt-4-v1.0"), "gpt-4");
assert_eq!(normalize_model_name("bedrock/claude-3-opus"), "claude-3-opus");
