build: add pre-commit hook gating lint + test + build

Browse source 
`.githooks/pre-commit` runs `make lint test build` on every commit,
catching unformatted Go (`gofmt -l`), `go vet` regressions, shellcheck
errors on scripts/, broken unit tests, and broken builds before they
reach the index. Activate per-clone with `make install-hooks`, which
points `core.hooksPath` at `.githooks/`. Bypass for in-flight WIP
commits with `git commit --no-verify`.

The hook directory is tracked in git (unlike .git/hooks/) so a clone
+ `make install-hooks` is enough to opt in; no per-machine
hand-installation. .PHONY and the help line both list the new
target.
