Start Phase 8 with pathlib

[RamonRDR]

Summary

• start Phase 8: Standard Library with Chapter 01, Working with Filesystem Paths Using pathlib, in English, Brazilian Portuguese, and Spanish
• establish multilingual Phase 8 section indexes and the planned nine-chapter standard-library learning path
• teach Path, pure paths, relative and absolute paths, portable path composition, structural inspection, cwd()/home(), read_text()/write_text(), Path.open(), directory creation, filesystem queries, iterdir(), glob()/rglob(), relative_to(), resolve(), path-like interoperability, cross-platform boundaries, and exception-aware filesystem operations
• explicitly teach that existence checks are snapshots rather than guarantees for later operations
• add four deterministic executable pathlib examples using path-only operations or temporary directories
• synchronize root status, localized status pages, learning paths, roadmaps, project-structure documents, and the approved example manifest
• mark Phase 8 as in progress and datetime as the next planned chapter

Validation

• EN / PT-BR / ES chapter Python blocks are aligned
• 37 fenced Python blocks are identical across all three chapter versions and syntax-checked with ast.parse
• 4 new executable examples, raising the approved manifest from 120 to 124 examples
• repository unit tests passed
• all 124 approved examples passed
• 1,914 internal Markdown links checked successfully
• repository structure validation passed
• git diff --check and Python compilation passed
• exactly 23 changed files
• one focused commit based exactly on main at 65c930ae4cb6bb0e5a138c628ec34f0c751aaefc
