Migrated all 80 app JSON files to place config_path inside each
install_methods object instead of at the root level. This allows
different install methods (e.g. Debian vs Alpine) to have distinct
config paths.
Also updated AGENTS.md JSON structure example to reflect the change.
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.
