Add memvid.com devcontainer feature

[Copilot]

Adds a devcontainer feature for installing the memvid CLI — an AI memory layer tool with semantic search over single-file .mv2 stores.

memvid ships as the memvid-cli npm package (no standalone binary release assets), so installation uses nodejs/npm via apt followed by npm install -g memvid-cli.

Changes

• src/memvid.com/devcontainer-feature.json — feature metadata; exposes a version option (latest or X.Y.Z)
• src/memvid.com/install.sh — installs nodejs, npm, ca-certificates via apt if absent, then installs the memvid-cli npm package at the requested version
• test/memvid.com/test.sh — verifies memvid --version exits successfully and outputs the word memvid
• .github/workflows/test.yaml — adds memvid.com to both test-autogenerated and test-scenarios matrix lists

Usage

"features": {
    "ghcr.io/devcontainer-community/devcontainer-features/memvid.com:1": {}
}

Pin a specific release:

"ghcr.io/devcontainer-community/devcontainer-features/memvid.com:1": {
    "version": "2.0.139"
}

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/memvid/memvid/releases/296903877/assets
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (http block)
  • 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)
