v0.4: Fixed Nix Installation

VS Code DevContainer v0.4

🔧 Critical Fix: Resolved Nix installation issues in Docker multi-platform builds!

🛠️ What's Fixed

• Nix Installation Moved - Now installed during post-creation for better compatibility
• Seccomp Issues Resolved - No more "unable to load seccomp BPF program" errors
• Multi-platform Support - ARM64 and AMD64 builds now work correctly
• Non-root Installation - Nix installs as the node user for proper permissions

🏗️ Technical Changes

• Nix installation moved from Dockerfile to post-container-creation.sh
• Smart user detection (installs as node user when run as root)
• Proper configuration for both root and non-root contexts
• Flakes and experimental features still enabled by default

📦 Full Toolchain (Unchanged)

• Node.js - JavaScript/TypeScript runtime
• Deno v2.2.1 - Modern JS/TS runtime
• Python with uv v0.6.2 - Fast Python package manager
• Nix - Now installs reliably with flakes support ✅
• Just - Command runner for project automation
• MongoDB - Database with mongosh and tools
• GitHub CLI - Git workflow automation

🚀 Usage

The Docker registry images will now build successfully! Choose your preferred method:

Pre-built Image (fastest):

"image": "ghcr.io/phily-me/vscode-devcontainer:v0.4"

Local Build (most flexible):
Keep the default dockerComposeFile configuration.

🔄 Migration

If you're using v0.3 or earlier, simply rebuild your devcontainer. Nix will install automatically during the post-creation phase.
