Major rewrite of PentestGPT to use an agentic pipeline architecture:

interface with ClaudeCodeBackend implementation - Session management
with file-based persistence for resumable pentests - Langfuse
integration for observability and tracing Interface: - New Textual-based
TUI with real-time activity feed - Keyboard shortcuts: F1 help, Ctrl+P
pause, Ctrl+Q quit - Enhanced CLI with --target, --instruction,
--non-interactive, --debug flags Project Structure: - Moved legacy
multi-LLM version (v0.15) to legacy/ directory - New pentestgpt/core/
for agent, controller, events, session modules - New
pentestgpt/interface/ for TUI and CLI components - New
pentestgpt/benchmark/ for xbow benchmark integration - Comprehensive
test suite in tests/ with unit and integration tests DevOps: - Docker
support with Ubuntu 24.04 container - GitHub Actions CI/CD pipeline -
Makefile with dev commands (test, lint, format, typecheck) - Added
