# ------------------------------------------------------------------------------
# Downloads and deploys latest GitHub release (source, binary, tarball, asset).
#
# Description:
#   - Fetches latest release metadata from GitHub API
#   - Supports the following modes:
#       - tarball: Source code tarball (default if omitted)
#       - source: Alias for tarball (same behavior)
#       - binary: .deb package install (arch-dependent)
#       - prebuild: Prebuilt .tar.gz archive (e.g. Go binaries)
#       - singlefile: Standalone binary (no archive, direct chmod +x install)
#   - Handles download, extraction/installation and version tracking in ~/.<app>
#
# Parameters:
#   $1   APP               - Application name (used for install path and version file)
#   $2   REPO              - GitHub repository in form user/repo
#   $3   MODE              - Release type:
#                              tarball   → source tarball (.tar.gz)
#                              binary    → .deb file (auto-arch matched)
#                              prebuild  → prebuilt archive (e.g. tar.gz)
#                              singlefile→ standalone binary (chmod +x)
#   $4   VERSION           - Optional release tag (default: latest)
#   $5   TARGET_DIR        - Optional install path (default: /opt/<app>)
#   $6   ASSET_FILENAME    - Required for:
#                              - prebuild  → archive filename or pattern
#                              - singlefile→ binary filename or pattern
#
# Optional:
#   - Set GITHUB_TOKEN env var to increase API rate limit (recommended for CI/CD).
#
# Examples:
#   # 1. Minimal: Fetch and deploy source tarball
#   fetch_and_deploy_gh_release "myapp" "myuser/myapp"
#
#   # 2. Binary install via .deb asset (architecture auto-detected)
#   fetch_and_deploy_gh_release "myapp" "myuser/myapp" "binary"
#
#   # 3. Prebuilt archive (.tar.gz) with asset filename match
#   fetch_and_deploy_gh_release "hanko" "teamhanko/hanko" "prebuild" "latest" "/opt/hanko" "hanko_Linux_x86_64.tar.gz"
#
#   # 4. Single binary (chmod +x) like Argus, Promtail etc.
