build: unify the gate so root make check covers the backend (closes #16 )

Root `make check` only ever ran the frontend, so the "main is always green" policy was satisfied vacuously: the Go backend could be entirely broken and the root gate stayed green. - The backend moves onto scripts-to-rule-them-all. Its test, lint, fmt, fmt-check, build, run and clean implementations now live in `backend/script/`, and `backend/Makefile` is thin shims. The backend is its own project (own module, README, LICENSE, linter config, Dockerfile stage), and `Dockerfile.backend` only copies `backend/` into its builder, so its scripts have to live under `backend/`. - The root `script/test`, `script/lint`, `script/fmt` and `script/fmt-check` now run the frontend step and then the matching `backend/script/*` step, so `script/check` — and therefore the pre-commit hook — gates both halves. The frontend-only steps moved into `script/frontend-*` so nothing is duplicated. - `script/bootstrap` now provisions the backend's toolchain as well, because widening the gate without widening bootstrap left the documented fresh-clone path (`make setup`) installing a pre-commit hook that rejected every commit with `golangci-lint: not found`. Go is reused when the installed version is new enough, otherwise it is installed from the official `go1.25.7` release archive; golangci-lint is installed at exactly `2.7.2`, the version `Dockerfile.backend` pins, so local findings match CI. Both come from a specific release archive whose sha256 is hardcoded here and verified before anything is unpacked — never an install script piped to a shell — and both are symlinked onto `PATH`, since nvm-style activation does not reach `make` or the git hook. - `script/frontend-check` is the frontend half of the gate, exposed as the `frontend-check` target, for the frontend Dockerfile: its build stage is a node image with no Go toolchain. The backend half is gated by `Dockerfile.backend`, and `script/cibuild` builds both images, so the two Dockerfiles together still gate the whole repo. The `backend-check` target is the mirror of it. Both targets are named after the script they shim, like every other target. - `script/cibuild` builds both images through one `build_image` helper, and the Gitea workflow's only build step is `script/cibuild`; the raw `docker build -f Dockerfile.backend .` is gone from the workflow. `script/docker` likewise builds and tags both images. - `backend/Makefile`'s `hooks` target is removed. It wrote the same `.git/hooks/pre-commit` as `script/install-precommit`, so the two clobbered each other and the developer silently ended up gating on only one half of the repo. `script/install-precommit` is now the only installer, and the hook it writes runs the repo-wide `script/check`. - `backend/Makefile`'s `docker` target is removed too: the backend image builds from the repo root with a root-level Dockerfile, so it belongs to the root `script/docker` and `script/cibuild` rather than to a backend script that would have to reach outside `backend/`. - `backend/script/lint` verifies that `.golangci.yml` still matches its pinned sha256 before running the linter. Offline hash comparison, no network. The pin is marked provisional in the file: it is the config currently on `main`, and the comment names PR #31 and the canonical hash that must replace it when #31 lands. - Every script locates the repo root with the mandated `$(cd "$(dirname "$0")/.." && pwd -P)` idiom, `cd`s there, and calls siblings as `"$ROOT/script/<name>"`; the `SCRIPT_DIR` variant is gone. READMEs at the root and in `backend/` document every script, the backend's Getting Started separates commands run from `backend/` from those run at the repo root, and `TODO.md` records the change.
