Add fathyb/carbonyl (id: fathyb-carbonyl) feature

[Copilot]

Adds a devcontainer feature for carbonyl, a Chromium-based browser that runs in a terminal.

New files

• src/fathyb-carbonyl/devcontainer-feature.json — metadata, version 1.0.0
• src/fathyb-carbonyl/install.sh — downloads carbonyl.linux-{amd64|arm64}.zip from GitHub Releases, extracts all files (binary + bundled shared libs) to /usr/local/lib/carbonyl/, symlinks binary to /usr/local/bin/carbonyl
• src/fathyb-carbonyl/NOTES.md — documents install path and arch constraints
• test/fathyb-carbonyl/test.sh — verifies carbonyl --version executes

Modified

• README.md — adds fathyb/carbonyl row in alphabetical order

Notes

Unlike single-binary features, carbonyl ships Chromium shared libraries alongside the binary (libcarbonyl.so, libGLESv2.so, etc.). The install script extracts all zip contents to a dedicated lib directory and strips the versioned subdirectory prefix (carbonyl-{version}/), then symlinks the binary. Only linux/amd64 and linux/arm64 are supported upstream.

Fixed in d08534e. The carbonyl binary is a Chromium-based app that requires system shared libraries (libnss3, libnspr4, libgbm1, libdrm2, libdbus-1-3, libxkbcommon0) which aren't present in a minimal Debian/Ubuntu container. Added an install_chromium_runtime_deps step to the install function to install these before running the binary.

Fixed in 10b3d45. The upstream carbonyl Dockerfile documents exactly four system deps (libasound2 libexpat1 libfontconfig1 libnss3). The install script now installs those, with a libasound2t64 || libasound2 fallback to handle the package rename introduced in Ubuntu 24+ and Debian 13.
