feat(mcp): add read_file tool and simplify edit/write returns

- edit_file: truncate diff to 15 lines, compact result format
- write_file: return only path/bytes/message
- read_file: new tool with multi-file, directory, regex support
  - paths: single file, array, or directory
  - pattern: glob filter (*.ts)
  - contentPattern: regex content search
  - maxDepth, maxFiles, includeContent options
- Update tool-strategy.md documentation
