v0.4.1 — OpenAI tool name sanitization

What's Changed

• OpenAI 64-char tool name limit: Added sanitizeToolName() in the OpenAI provider that replaces invalid characters and truncates names exceeding 64 chars with a deterministic hash suffix
• Reverse mapping: Tool call responses from OpenAI are mapped back to original names transparently — other providers (Anthropic, Gemini) are unaffected
• toolPrefix on McpHttpConfig: Empty string prefix now correctly skips namespacing

Files Changed

• src/providers/openai.ts — sanitize + truncate + bidirectional name mapping
• tests/providers/openai.test.ts — sanitization tests
• tests/integration.test.ts — path fix
