Top of the stack, stacked on the Spec author PR. Adds DEV-385: every function is exported so a test can call it directly, and each function a PR adds or changes gets a unit test in that PR. The tests run in the pre-commit hook, next to the lint from DEV-380, so a failure blocks the commit locally, and the same tests run in CI so a skipped hook cannot merge.

1. Run the tests in the `pre-commit` hook of the repository's `lefthook.yml`,
the same hook that runs lint per [DEV-380](./DEV-380.md), so a failing test
blocks the commit locally.
1. Run the same tests in CI on every pull request, so a commit that skipped the
hook still cannot merge.

Wire the DEV-385 test gate.

DEV-385 is marked active and automated, but package.json declares no test command. lefthook.yml runs only Markdown and rules checks. Define the repository test command and add it to pre-commit. The existing PR workflow invokes that hook, so the same command will then run in CI.
