feat: v3 Go rewrite — full artifact proxy with web UI, TUI, and Terraform provider

Complete rewrite of ArtifactAPI from Python/FastAPI to Go as a single binary. Core engine: - 10 package providers: generic, docker, helm, pypi, npm, rpm, alpine, puppet, terraform, goproxy — each with built-in mutable patterns - Content-addressable storage (SHA256 dedup across all remotes) - Three-tier caching: Redis (TTL/locks) → S3/MinIO (blobs) → upstream - Classifier with allowlist/blocklist per-remote (empty = allow all) - Circuit breaker, conditional revalidation, stale-on-error - Background garbage collection for orphaned blobs - Access logging to PostgreSQL API: - v1 proxy endpoints (backwards compatible) - v2 management API: CRUD remotes/virtuals, object browser, stats, health, SSE events, probe/test endpoint - Virtual repos with index merging (Helm YAML + PyPI HTML) Frontend (React + Vite, separate Dockerfile): - Dashboard with stats, health indicators, top remotes - Remotes list with type filter, remote detail with config/patterns - Object browser with pagination and evict - Test Remote page: probe any remote path, see headers/size/timing - Virtuals page with expandable member lists TUI (Bubble Tea): - Dashboard, remotes list/detail, object browser, virtuals - Vim-style navigation, artifactapi tui --endpoint <url> Infrastructure: - S3 client supports MinIO, Ceph RGW, AWS S3 (minio-go) - PostgreSQL schema with migrations - Docker Compose: API + UI + Postgres 17 + Redis 7 + MinIO - Makefile with Go version check, build/test/lint/fmt/e2e targets - Distroless Docker image (~15MB) Testing: - Unit tests for models, classifier, providers, mergers - E2E tests with testcontainers-go (real Postgres/Redis/MinIO) Terraform config: - All 40 production remotes + helm virtual as HCL - Provider repo: terraform-provider-artifactapi v0.0.1 (separate)
