MCP LLDB v0.1.0 🎉

First release of the Rust implementation of MCP LLDB server for macOS debugging — core dump analysis, remote debugging, and direct program debugging.

🚀 Features

Core Dump Analysis: Open and analyze macOS core dump files with backtrace, threads, and shared library info
Remote Debugging: Connect to debugserver targets via host:port
Direct Program Debugging: Launch executables under LLDB, set breakpoints, step through code, inspect variables
Custom Commands: Execute arbitrary LLDB commands in active sessions
Session Management: Automatic session pooling, reuse, and dead session eviction
Crash File Discovery: Search and list core dump and crash report files (supports core, core.*, *.ips, *.crash patterns)

open_lldb_core — Analyze core dump files with optional backtrace, threads, and shared libraries
open_lldb_remote — Connect to debugserver remote targets
launch_debug — Launch programs under LLDB for interactive debugging
run_lldb_cmd — Execute custom LLDB commands in any session
close_lldb_core — Close core dump sessions
close_lldb_remote — Close remote debugging sessions
close_debug — Close launch debug sessions and terminate target program
list_crash_files — List available core dumps and crash reports from macOS system paths

✅ High Performance: Native Rust implementation with Tokio async runtime
✅ Memory Safe: Compile-time memory safety guarantees
✅ Single Binary: No runtime dependencies
✅ MCP Protocol: Full Model Context Protocol support via stdio transport
✅ Session Pooling: Automatic LLDB session reuse and dead session eviction
✅ Configurable Timeouts: Separate init timeout (symbol loading) and command timeout
✅ dSYM Support: Load .dSYM symbol bundles for stripped binaries
✅ Universal Binary: Architecture selection for fat binaries (arm64 / x86_64)
✅ DevToolsSecurity Detection: Pre-launch checks with clear error messages
✅ SIP Awareness: Warns when debugging SIP-protected system paths
✅ Hardened Runtime Hints: Suggests get-task-allow entitlement or codesign --remove-signature on permission errors
