//! deep context, TDG, provability, and comprehensive analysis.

/// Performs comprehensive analysis of project context, including code relationships,
/// dependencies, and architectural patterns. This addresses issue #33 where the
/// command wasn't finding anything by implementing proper file discovery and analysis.
