Add Makefile shims for cibuild and precommit (closes #34)

script/cibuild and script/precommit both existed and were already the
documented CI and pre-commit entrypoints, but neither had a Makefile
target, so the standing rule to drive the repo through make targets
rather than the underlying tool could not be followed for either.

It matters most for the build. A bare `docker build .` fails closed on
the CHECK_EPOCH guard by design, so script/cibuild is one of only three
supported ways to build an image here, and it was the only one of the
three without a target while `make docker` had one.

The two targets are thin shims in the same style as every other target
and change nothing about what the scripts do. .PHONY was already
complete for the targets that existed and now lists both new ones.

README.md's Entrypoints section gains the script-to-target mapping so
the two documents agree, including the two names that do not match:
script/install-precommit is `make hooks`, and script/precommit is
`make precommit`. It also warns that `make cibuild` runs two container
builds and costs minutes, so nobody types it expecting the runtime the
other make targets have.

+  `docker build .` fails closed on the `CHECK_EPOCH` guard, so `script/cibuild`
+  is one of only three supported ways to build an image and was the only one

+  change nothing about what the scripts do. `.PHONY` was already complete and
