David Peter 47956db567 [red-knot] Specialize str.startswith for string literals (#17351) ... ## Summary Infer precise Boolean literal types for `str.startswith` calls where the instance and the prefix are both string literals. This allows us to understand `sys.platform.startswith(…)` branches. ## Test Plan New Markdown tests		2025-04-11 16:26:45 +02:00
