Add degoog CT/install/metadata and update docs

Introduce degoog support: add ct/degoog.sh (container orchestration and update handler), install/degoog-install.sh (in-container install using Bun, deploy prebuilt release, create systemd service on port 4444) and json/degoog.json (app metadata and default resources). ct script includes update routine with backups, Bun install, and fetch_and_deploy_gh_release usage. Also update documentation: refine contribution guide (CONTRIBUTING.md) with fork/testing workflow, templates, and metadata guidance; expand misc README to reflect canonical misc/* function library responsibilities and references.
