adding verbose mode, readme info for environment, and cleanup

[sam1el]

Summary

Improves the org project cycle script so large and automation-heavy runs are safer, clearer, and faster: preview without writes, better observability, optional “activate only inactive” mode, an extra SCM origin, and thread-pool workers for parallel API calls.

Note: The branch is named feat/dry-run, but the change set is broader (UX + scale for the same tool), not only dry-run.

What changed

• --dry-run — List orgs, filters, and the projects that would be cycled (or activated) without calling deactivate/activate.
• -v / --verbose — Extra logging (environment URLs, org visibility, per-request details).
• README — Reworked quick start, cheat sheet table, region/environment, auth, and large-org notes (includes --workers, OAuth vs token, FedRAMP reminder).
• --activate-inactive-only — Skip the deactivate pass; only activate projects that are already inactive (re-monitor).
• Origins — Support github-cloud-app as an import origin (alongside e.g. github, gitlab).
• --workers N — Parallel deactivate/activate via a thread pool (1–64); when > 1, requires credentials in the environment (no interactive token prompt). yaspin added for progress in parallel runs.
• Tooling — Local .vscode/settings.json in the subfolder (editor defaults for this project).

Files

• deactivate-reactivate/main.py — CLI flags, dry-run/verbose/parallel paths, github-cloud-app in origin help.
• deactivate-reactivate/README.md — User-facing documentation aligned with the new flags.
• deactivate-reactivate/requirements.txt — New dependencies for the updated script.

How to test

1. pip install -r deactivate-reactivate/requirements.txt
2. python3 main.py --orgs <slug> --dry-run and confirm listed orgs/projects and no writes.
3. python3 main.py --orgs <slug> --dry-run -v and confirm verbose output.
4. Optional: --origins github github-cloud-app / --activate-inactive-only / --workers 4 with SNYK_TOKEN (or OAuth) in the environment.
