Add rclone.org devcontainer feature

[Copilot]

Adds a new devcontainer feature to install the rclone binary from GitHub releases.

Changes

• src/rclone.org/ — New feature with devcontainer-feature.json, install.sh, and README.md
  • Downloads the versioned .zip release artifact from GitHub (rclone ships zip, not tar.gz)
  • Architecture mapping: amd64, arm64, arm-v7, 386
  • Installs unzip via apt if not present; extracts binary to /usr/local/bin/rclone
  • Supports latest (default) or pinned X.Y.Z version
• test/rclone.org/test.sh — Verifies rclone --version executes successfully
• .github/workflows/test.yaml — Adds rclone.org to both test-autogenerated and test-scenarios matrices

Usage

"features": {
    "ghcr.io/devcontainer-community/devcontainer-features/rclone.org:1": {}
}

Pin to a specific version:

"features": {
    "ghcr.io/devcontainer-community/devcontainer-features/rclone.org:1": {
        "version": "1.73.2"
    }
}

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/repos/rclone/rclone/releases
  • Triggering command: /usr/bin/curl curl -s REDACTED (http block)
• https://api.github.com/repos/rclone/rclone/releases/latest
  • Triggering command: /usr/bin/curl curl -s REDACTED (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
