fix: Make containers buildable and add smoke test
This commit makes Project Wharf actually runnable: ## Container Fixes - Use standard Alpine-based images (php:8.3-fpm-alpine, nginx:alpine) - Fix user/group configuration for non-root operation - Add agent.Dockerfile with multi-stage Rust build - Fix nginx.conf to omit 'user' directive (runs as container user) - Fix php-fpm.conf to use www-data user ## Build Fixes - Exclude wharf-ebpf from default workspace (requires special toolchain) - Fix Rust edition from 2024 to 2021 (2024 doesn't exist yet) ## Testing - Add scripts/smoke_test.sh for quick sanity checks - Add 'just smoke-test' and 'just smoke-test-full' recipes - Tests: prerequisites, Rust compilation, container builds, config validation ## Quick Start 1. just smoke-test # Check prerequisites 2. just smoke-test-full # Build and test containers 3. cargo build --release # Build Rust binaries 4. just build-containers # Build production images The Yacht can now actually be deployed.
