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.
Introduced new and updated documentation files across the docs/ directory, including project structure guides, function library references, and standardized READMEs for ct, install, vm, tools, api, and misc. This update fully documents all nine function libraries, provides quick start and learning paths, and mirrors the project structure for easier navigation and contribution.
