Prerelease: no

Release notes:

What's changed

• Spawn failures on an existing native binary now explain the likely libc mismatch (musl binary on a glibc host) and suggest options.pathToClaudeCodeExecutable
• Permission-denied advisory messages now carry typed denial reasons (safetyCheck, asyncAgent), enabling SDK consumers to programmatically match denial causes
• Fixed UserPromptSubmit hook block feedback not being emitted to the SDK event stream — consumers can now see why a prompt was blocked by a hook instead of a silent hang
• Remote Control workers now send a worker_shutting_down system message on graceful exit so remote clients can show why the session ended
• Fixed MCP server-level specs (mcp__server, mcp__server__*) in disallowedTools being silently ignored — they now correctly remove all tools from the named server
