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.
Add container templates, install scripts and metadata for six applications: BirdNET-Go, ERPNext, Jitsi Meet, Storybook, Storyteller and Tube Archivist. New files include ct/* scripts (container templates and update handlers), install/* scripts (installation and systemd service setup, dependency installation and build steps) and json/* metadata entries (app catalog data, default resources, ports and notes). Each install script configures required dependencies, creates services, and prepares runtime configuration (e.g. DB, ElasticSearch, Node/Python environments, ffmpeg/Readium). This commit enables automated LXC provisioning and update flows for these apps.
