docs: update CONTRIBUTING.md with correct commands and tool names

- Update tool references from pia_search to pia_search_content
- Fix pre-commit configuration to match actual .pre-commit-config.yaml
- Update pre-commit hooks description to reflect actual functionality:
  - File formatting (trailing whitespace, end-of-file)
  - YAML/JSON validation
  - Merge conflict detection
  - Large file prevention
- Verify all commands work correctly with current project structure
- Update code examples with current function names

All commands and examples now match the current implementation

-- **Linting**: Checks for code quality issues
-- **File Checks**: Ensures proper file formatting and structure
+- **File Checks**: Removes trailing whitespace, fixes end-of-file formatting
+- **YAML/JSON Validation**: Checks syntax of configuration files
