chore: format with treefmt

Apply consistent formatting across the repository using nix fmt:
- YAML files: standardise string quoting to double quotes
- Markdown files: add blank lines before lists for proper rendering
- Remove trailing whitespace in CLAUDE.md

 ### OpenAPI Specifications
 
 All tool definitions are generated from OpenAPI specs in `stackone_ai/oas/`:
+
 - `core.json`, `ats.json`, `crm.json`, `documents.json`, `hris.json`, `iam.json`, `lms.json`, `marketing.json`
 
 ## Key Development Patterns
 
 ### Tool Filtering
+
 ```python
 # Use glob patterns for tool selection
 tools = StackOneToolSet(include_tools=["hris_*", "!hris_create_*"])
 ```
 
 ### Authentication
+
 ```python
 # Uses environment variables or direct configuration
 toolset = StackOneToolSet(

 ### Type Safety
+
 - Full type annotations required (Python 3.11+)
 - Strict mypy configuration
 - Use generics for better IDE support
 
 ### Testing

 - Snapshot testing for tool parsing (`tests/snapshots/`)
 - Async tests use `pytest-asyncio`
 - Example validation: See @./.cursor/rules/examples-standards

 ## Common Tasks
 
 ### Adding New SaaS Integration
+
 1. Add OpenAPI spec to `stackone_ai/oas/`
 2. Parser automatically converts to tool definitions
 3. Test with `make test-tools`
 
 ### Modifying Tool Behavior
+
 - Core execution logic in `StackOneTool.execute()` method
 - HTTP configuration via `ExecuteConfig` class
 - Response handling in `_process_response()`
 
 ### Updating Documentation
+
 - Examples requirements: See @./.cursor/rules/examples-standards
 - Run `make docs-serve` to preview changes
 - MkDocs config in `mkdocs.yml`

 - `fetch_tools()` uses keyword arguments for all filtering
 - `account_id` becomes `account_ids` (list)
 - Filter patterns go in the `actions` parameter (list)
