-//! Language-specific analysis implementations
-//!
-//! This module contains language-specific parsing logic and tree-sitter queries
-//! for the analyze tool. Each language has its own submodule with query definitions
-//! and optional helper functions.
-//!
-//! ## Adding a New Language
-//!
-//! To add support for a new language:
-//!
-//! 1. Create a new file `languages/yourlang.rs`
-//! 2. Define `ELEMENT_QUERY` and `CALL_QUERY` constants
-//! 3. Optionally define `REFERENCE_QUERY` for advanced type tracking
-//! 4. Add `pub mod yourlang;` below
-//! 5. Add language configuration to registry in `get_language_info()`
-//!
-//! ## Optional Features
-//!
-//! Languages can opt into additional features by implementing:
-//!
-//! - Reference tracking: Define `REFERENCE_QUERY` to track type instantiation,
-//!   field types, and method-to-type associations (see Go and Ruby)
-//! - Custom function naming: Implement `extract_function_name_for_kind()` for
-//!   special cases like Swift's init/deinit or Rust's impl blocks
-//! - Method receiver lookup: Implement `find_method_for_receiver()` to associate
-//!   methods with their containing types (see Go and Ruby)

-# Enhanced Code Editing with AI Models
-
-The developer extension now supports using AI models for enhanced code editing through the `str_replace` command. When configured, it will use an AI model to intelligently apply code changes instead of simple string replacement.
-
-## Configuration
-
-Set these environment variables to enable AI-powered code editing:
-
-```bash
-export GOOSE_EDITOR_API_KEY="your-api-key-here"
-export GOOSE_EDITOR_HOST="https://api.openai.com/v1"
-export GOOSE_EDITOR_MODEL="gpt-4o"
-```
-
-**All three environment variables must be set and non-empty for the feature to activate.**
-
-### Supported Providers
-
-Any OpenAI-compatible API endpoint should work. Examples:
-
-**OpenAI:**
-```bash
-export GOOSE_EDITOR_API_KEY="sk-..."
-export GOOSE_EDITOR_HOST="https://api.openai.com/v1"
-export GOOSE_EDITOR_MODEL="gpt-4o"
-```
-
-**Anthropic (via OpenAI-compatible proxy):**
-```bash
-export GOOSE_EDITOR_API_KEY="sk-ant-..."
-export GOOSE_EDITOR_HOST="https://api.anthropic.com/v1"
-export GOOSE_EDITOR_MODEL="claude-sonnet-4-20250514"
-```
-
-**Morph:**
-```bash
-export GOOSE_EDITOR_API_KEY="sk-..."
-export GOOSE_EDITOR_HOST="https://api.morphllm.com/v1"
-export GOOSE_EDITOR_MODEL="morph-v3-large"
-```
-
-**Relace**
-```bash
-export GOOSE_EDITOR_API_KEY="rlc-..."
-export GOOSE_EDITOR_HOST="https://instantapply.endpoint.relace.run/v1/apply"
-export GOOSE_EDITOR_MODEL="auto"
-```
-
-**Local/Custom endpoints:**
-```bash
-export GOOSE_EDITOR_API_KEY="your-key"
-export GOOSE_EDITOR_HOST="http://localhost:8000/v1"
-export GOOSE_EDITOR_MODEL="your-model"
-```
-
-## How it works
-
-When you use the `str_replace` command in the text editor:
-
-1. **Configuration check**: The system first checks if all three environment variables are properly set and non-empty.
-
-2. **With AI enabled**: If configured, the system sends the original code and your requested change to the configured AI model, which intelligently applies the change while maintaining code structure, formatting, and context.
-
-3. **Fallback**: If the AI API is not configured or the API call fails, it falls back to simple string replacement as before.
-
-4. **User feedback**: The first time you use `str_replace` without AI configuration, you'll see a helpful message explaining how to enable the feature.
-
-## Benefits
-
-- **Context-aware editing**: The AI understands code structure and can make more intelligent changes
-- **Better formatting**: Maintains consistent code style and formatting
-- **Error prevention**: Can catch and fix potential issues during the edit
-- **Flexible**: Works with any OpenAI-compatible API
-- **Clean implementation**: Uses proper control flow instead of exception handling for configuration checks
-
-## Implementation Details
-
-The implementation follows idiomatic Rust patterns:
-- Environment variables are checked upfront before attempting API calls
-- No exceptions are used for normal control flow
-- Clear separation between configured and unconfigured states
-- Graceful fallback behavior in all cases
-
-The feature is completely optional and backwards compatible - if not configured, the system works exactly as before with simple string replacement.

-        This will be read by a less intelligent model, which will quickly apply the edit. You should make it clear what the edit is, while also minimizing the unchanged code you write.
-        
-        **IMPORTANT**: in the new_str parameter, you must also provide an `instruction` - a single sentence written in the first person describing what you are going to do for the sketched edit. 
-        This instruction helps the less intelligent model understand and apply your edit correctly. 
-
-         Examples of good instructions:
-        - I am adding error handling to the user authentication function and removing the old authentication method
-        - The instruction should be specific enough to disambiguate any uncertainty in your edit.
-        
-
-        The format for new_str should be like this example: 
-
-        <code>
-          new code here you want to add 
-        </code>
-        <instruction>
-         adding new code with error handling
-        </instruction>
-
-        provide this to new_str as a single string.
-
-        When writing the edit, you should specify each edit in sequence, with the special comment // ... existing code ... to represent unchanged code in between edited lines.
-
-        For example:
-        // ... existing code ...
-        FIRST_EDIT
-        // ... existing code ...
-        SECOND_EDIT
-        // ... existing code ...
-        THIRD_EDIT
-        // ... existing code ...
-
-        You should bias towards repeating as few lines of the original file as possible to convey the change.
-        Each edit should contain sufficient context of unchanged lines around the code you're editing to resolve ambiguity.
-        If you plan on deleting a section, you must provide surrounding context to indicate the deletion.
-        DO NOT omit spans of pre-existing code without using the // ... existing code ... comment to indicate its absence.
