feat(ci): expand port matrix to all 13 platforms + bump deprecated actions

- Add 20 matrix entries: copilot, augment, cline, kilo, kiro, gemini, opencode, roo, windsurf, agents (PS+Py each)
- Total: 25 port-* branches (Claude Code PS = main, plus 13 × Py + 12 × PS)
- Bump actions/checkout@v4 → @v5, actions/setup-python@v5 → @v6 (removes Node.js 20 deprecation warnings)
- README: replace "соберите локально" placeholders with real branch links for all platforms

-Готовые ветки `port-*` пересобираются автоматически на каждое изменение в навыках. Платформы со статусом «соберите локально» — на стадии расширения матрицы; пока ставятся [через `switch.py`](#альтернативный-способ--собрать-локально-через-switchpy).
+Готовые ветки `port-*` пересобираются автоматически на каждое изменение в навыках. Если нужна свежая сборка прямо сейчас — соберите [локально через `switch.py`](#альтернативный-способ--собрать-локально-через-switchpy).
 
 Некоторые платформы (Augment, Cline, VS Code/Copilot) также сканируют `.claude/skills/` как fallback — для них достаточно `main`.
