feat: add onecli.sh-cli devcontainer feature

[Copilot]

Adds a new devcontainer feature to install the onecli CLI — a terminal tool for managing agents, secrets, rules, and configuration via the OneCLI platform.

Changes

• src/onecli.sh-cli/devcontainer-feature.json — feature manifest, id onecli.sh-cli, version 1.0.0, version option defaulting to latest
• src/onecli.sh-cli/install.sh — gh release install method using the canonical fzf-style template; downloads onecli_${version}_linux_${architecture}.tar.gz from onecli/onecli-cli releases (binary at archive root, standard Go amd64/arm64 arch labels)
• src/onecli.sh-cli/NOTES.md — project link, description, install method docs
• test/onecli.sh-cli/test.sh — smoke test via onecli --version
• README.md — table row added alphabetically between nvidia.com/cuda and opencode.ai

Fixed in 2f9aa92. The onecli binary doesn't support a --version flag — it returns a JSON error. It uses a version subcommand instead (onecli version → {"version": "1.1.0"}). Updated both test/onecli.sh-cli/test.sh and versionArgument in install.sh accordingly.
