feat: smart integration detection — auto-classify packages via built-in dictionary, PyPI lookup, and project module filtering

- New package_classifier.rs with 200+ known packages in 8 categories
- Python stdlib filter (~170 modules)
- PyPI API lookup with caching (--offline to skip)
- Project modules auto-filtered from Internal
- Zero config needed — works out of the box

+# PR: Major improvements to WTIsMyCode
+
+## Summary
+
+Comprehensive refactoring and feature additions to WTIsMyCode — the Python architecture documentation generator. This PR improves code quality, adds new features, and significantly enhances the development experience.
+
+**Stats:** 24 files changed, ~3900 insertions, ~1400 deletions, 50 tests
+
+## Changes
+
+### 🏗️ Architecture
+- **Decomposed monolithic `main.rs`** into `commands/` module structure (generate, init, check, stats)
+- **Added workspace `Cargo.toml`** for unified builds across both crates
+- **New `cycle_detector` module** with DFS-based dependency cycle detection
+
+### 🐍 Python Analyzer
+- **Full AST traversal** — properly walks all statement types (if/for/while/try/with/match)
+- **Function signatures** — extracts parameter names, types, defaults, return types
+- **Method detection** — distinguishes methods from standalone functions via `self`/`cls` parameter
+- **Docstring extraction** — parses first line of docstrings for symbol documentation
+- **Module path computation** — correctly computes module IDs from `src_roots` config
+
+### ✨ New Features
+- **`stats` command** — project statistics with colored output and progress bar
+- **Config validation** — validates project root, language, scan paths, cache age, file size formats
+- **Cycle detection** — finds circular dependencies in module graph, shown in critical points section
+- **`--dry-run` flag** — preview what would be generated without writing files
+- **Dynamic project data** — uses config project name and current date instead of hardcoded values
+- **Real usage examples** — generates Python import/call examples from analyzed symbols
+- **Skip-unchanged optimization** — writer skips files that haven't changed
+
+### 🧹 Code Quality
+- **Zero `unwrap()` calls** in non-test code — proper error handling throughout
+- **Zero clippy warnings** — all lints resolved
+- **50 tests** — unit tests for config validation, cycle detection, caching, integration detection, error handling, and full pipeline integration tests
+
+### 📚 Documentation
+- **README.md** — badges, full command reference, configuration table, architecture overview
+- **CHANGELOG.md** — complete changelog for this branch
+
+## Testing
+
+```bash
+cargo test        # 50 tests, all passing
+cargo clippy      # 0 warnings
+cargo build       # clean build
+```
+
+## Breaking Changes
+
+None. All existing functionality preserved.

-# ArchDoc
+# WTIsMyCode
 
-ArchDoc is a tool for automatically generating architecture documentation for Python projects. It analyzes your Python codebase and creates comprehensive documentation that helps developers understand the structure, dependencies, and key components of the project.
+![Rust](https://img.shields.io/badge/Rust-1.85%2B-orange?logo=rust)
+![License](https://img.shields.io/badge/License-MIT-blue)
+![Tests](https://img.shields.io/badge/Tests-50%20passing-brightgreen)
+
+**Automatic architecture documentation generator for Python projects.**
+
+WTIsMyCode analyzes your Python codebase using AST parsing and generates comprehensive Markdown documentation covering module structure, dependencies, integration points, and critical hotspots.
 
 ## Features
 
-- **Automatic Documentation Generation**: Automatically generates architecture documentation from Python source code
+- **AST-Based Analysis** — Full Python AST traversal for imports, classes, functions, calls, and docstrings
-- **AST-Based Analysis**: Uses Python AST to extract imports, definitions, and function calls
+- **Dependency Graph** — Module-level and file-level dependency tracking with cycle detection
-- **Diff-Aware Updates**: Preserves manual content while updating generated sections
+- **Integration Detection** — Automatically identifies HTTP, database, and message queue integrations
-- **Caching**: Caches analysis results for faster subsequent runs
+- **Diff-Aware Updates** — Preserves manually written sections while regenerating docs
-- **Configurable**: Highly configurable through `archdoc.toml`
+- **Caching** — Content-hash based caching for fast incremental regeneration
-- **Template-Based Rendering**: Uses Handlebars templates for customizable output
+- **Config Validation** — Comprehensive validation of `wtismycode.toml` with helpful error messages
+- **Statistics** — Project-level stats: file counts, symbol counts, fan-in/fan-out metrics
+- **Consistency Checks** — Verify documentation stays in sync with code changes
 
 ## Installation
 
-To install ArchDoc, you'll need Rust installed on your system. Then run:
+Requires Rust 1.85+:
 
 ```bash
-cargo install --path archdoc-cli
+cargo install --path wtismycode-cli
 ```
 
-## Usage
+## Quick Start
-
-### Initialize Configuration
-
-First, initialize the configuration in your project:
 
 ```bash
-archdoc init
+# Initialize config in your Python project
+wtismycode init
+
+# Generate architecture docs
+wtismycode generate
+
+# View project statistics
+wtismycode stats
+
+# Check docs are up-to-date
+wtismycode check
 ```
 
-This creates an `archdoc.toml` file with default settings.
+## Commands
 
-### Generate Documentation
+### `wtismycode generate`
 
-Generate architecture documentation for your project:
+Scans the project, analyzes Python files, and generates documentation:
 
-```bash
+```
-archdoc generate
+$ wtismycode generate
+🔍 Scanning project...
+📂 Found 24 Python files in 6 modules
+🔬 Analyzing dependencies...
+📝 Generating documentation...
+✅ Generated docs/architecture/ARCHITECTURE.md
+✅ Generated 6 module docs
 ```
 
-This will create documentation files in the configured output directory.
+Output includes:
+- **ARCHITECTURE.md** — Top-level overview with module index, dependency graph, and critical points
+- **Per-module docs** — Detailed documentation for each module with symbols, imports, and metrics
+- **Integration map** — HTTP, database, and queue integration points
+- **Critical points** — High fan-in/fan-out symbols and dependency cycles
 
-### Check Documentation Consistency
+### `wtismycode stats`
 
-Verify that your documentation is consistent with the code:
+Displays project statistics without generating docs:
 
-```bash
+```
-archdoc check
+$ wtismycode stats
+📊 Project Statistics
+  Files:    24
+  Modules:  6
+  Classes:  12
+  Functions: 47
+  Imports:  89
+  Edges:    134
 ```
 
-## Configuration
+### `wtismycode check`
 
-ArchDoc is configured through an `archdoc.toml` file. Here's an example configuration:
+Verifies documentation consistency with the current codebase:
+
+```
+$ wtismycode check
+✅ Documentation is up-to-date
+```
+
+Returns non-zero exit code if docs are stale — useful in CI pipelines.
+
+### `wtismycode init`
+
+Creates a default `wtismycode.toml` configuration file:
+
+```
+$ wtismycode init
+✅ Created wtismycode.toml with default settings
+```
+
+## Configuration Reference

+
+### Example Configuration

 ## How It Works
 
-1. **Scanning**: ArchDoc scans your project directory for Python files based on the configuration
+1. **Scan** — Walks the project tree, filtering by include/exclude patterns
-2. **Parsing**: It parses each Python file using AST to extract structure and relationships
+2. **Parse** — Parses each Python file with a full AST traversal (via `rustpython-parser`)
-3. **Analysis**: It analyzes the code to identify imports, definitions, and function calls
+3. **Analyze** — Builds a project model with modules, symbols, edges, and metrics
-4. **Documentation Generation**: It generates documentation using templates
+4. **Detect** — Identifies integration points (HTTP, DB, queues) and dependency cycles
-5. **Output**: It writes the documentation to files, preserving manual content
+5. **Render** — Generates Markdown using Handlebars templates
+6. **Write** — Outputs files with diff-aware updates preserving manual sections
