Stamp Docker image version from the host; flush profiles on error exit (closes #75)
script/docker and script/cibuild compute the version (via script/version),
commit and build date on the host and pass them as build args; the
Dockerfile no longer runs git, which always returned "unknown" because
the build context excludes .git. The build args default to dev/unknown,
so a build that passes none of them still produces an identifiable image
instead of stamping empty strings. A dirty tree is reflected through
script/version's -dirty suffix.

main now exits via os.Exit(run()), so its deferred CPU/heap profile
writers flush before the process ends, and Entry returns a status code
instead of calling os.Exit. Each command ran its operation in an fx
goroutine that called os.Exit(1) on failure, discarding those profiles
and the PID-lock release; they now route the error to the return path
through one RunOperation helper. errReported keeps Entry from printing an
already-reported failure twice.

# script/docker: build the Docker image tagged with the project name.

# Generic: needs no adaptation.

# This builds the PRODUCT image only, and the product Dockerfile has no
# lint stage: linting lives in Dockerfile.lint and is run by
# script/lint. So a green here means `make fmt-check` and `make test`
# passed and the image built -- it says nothing about lint. The gates
# are script/check (which runs script/lint) and script/cibuild (which
# builds both files).

# is almost always warm, so without this it would report a green the
# tree had not earned and the two entrypoints would disagree about
# whether the tree is clean. The Dockerfile now refuses to build

# every image a "commit: unknown" it could not be traced from.
