Stand up the Go project alongside the Python backend so both run
independently during migration. `make web-go` builds and serves on :8080;
`make web-py` (alias: `make web`) keeps the Python side on :5001.
- go/: new module `fuj-management/go` (Go 1.26)
- cmd/fuj: stdlib-flag dispatcher; `server` + `version` work,
fees/reconcile/sync/infer stubbed for M2/M4
- internal/config: env loader mirroring scripts/config.py
- internal/logging: slog setup, level taken from config
- internal/web: net/http ServeMux + request-timer middleware
- build/Dockerfile: golang:1.26 → alpine:3 multi-stage image
- .golangci.yml: govet, staticcheck, errcheck, gofumpt, unused
- Makefile: web→web-py alias; go-build/go-test/go-run/go-lint/web-go
- CI: parallel build-go job in .gitea/workflows/build.yaml (<tag>-go image)
- docs/plans/: M1 kickoff plan + progress tracker (M1 complete)
- .claude/settings.json: gofumpt + golangci-lint permissions
Gate: make go-build ✓ make go-lint ✓ make go-test ✓ curl :8080 ✓
