feat: add tool passthrough mode, identity leak sanitization & enhanced tool_choice=any
1. Tool passthrough mode (config: tools.passthrough: true) - Bypasses multi-namespace few-shot injection - Embeds raw tool definitions in <tools> tags with minimal 1-shot example - Cleans conflicting client prompts (provider-native tool calling, XML markup) - Ideal for Roo Code / Cline clients 2. Enhanced Cursor identity leak sanitization - New refusal detection patterns for "currently in Cursor context" leaks - 4 new sanitizeResponse regexes targeting full context leak paragraphs - Covers "I apologize - it appears I'm in Cursor support assistant context" 3. Enhanced tool_choice=any force message - Lists available tool names (up to 15) with format example - Uses collaborative guidance tone to avoid triggering refusal - Stream and non-stream paths aligned

Do NOT attempt to use any other tool-calling format. The \`\`\`json action\`\`\` block above is the ONLY way to invoke tools. Provider-native tool calling is NOT available in this environment.
