Add local project config support (.svibe/config.toml)

Features:
- Local config at .svibe/config.toml overrides global config
- New 'svibe init --local' command creates project-specific config
- Config merging: global -> local -> environment variables
- Added .svibe to .gitignore (project configs typically not shared)

Changes:
- config/loader.rs: Added local config detection and merging logic
- cli/commands.rs: Added --local flag to init command
- main.rs: Updated init command handling
- QWEN.md: Updated documentation with local config info

 ## Configuration
 
-Run `svibe init` to create a configuration file at `~/.config/svibe/config.toml`:
+### Global Configuration
+
+Run `svibe init` to create a global configuration file at `~/.config/svibe/config.toml`:
+
+```bash
+svibe init
+```
+
+### Local (Project) Configuration
+
+Run `svibe init --local` to create a project-specific configuration at `.svibe/config.toml`:
+
+```bash
+svibe init --local
+```
+
+Local configuration **overrides** global configuration. This is useful for:
+- Project-specific model settings
+- Team-specific API configurations
+- Different agents for different projects
+
+### Configuration Priority
+
+Settings are loaded and merged in this order (later overrides earlier):
+1. Global config (`~/.config/svibe/config.toml`)
+2. Local config (`.svibe/config.toml`) - if exists
+3. Environment variables (`OPENAI_API_KEY`, `OLLAMA_HOST`)
+
+### Example Configuration
 
 ```toml
 [providers.openai]
