Work spec creation guide should require build verification subtasks

[wtmoose]

Friction

An LLM completed all work spec implementation tasks and marked them done without ever running a build. The code had a compile error that was only caught when the human asked "Did you compile the code?" The work spec implementation guide says "Test for linter errors if applicable" but building is not a procedural rule — it's a subtask like any other. The work spec creation guide should ensure build verification is included.

Suggestion

Update the work spec creation guide to require build verification as a subtask: a common subtask after each implementation task where feasible, and a required final subtask before the work spec can be marked complete.

Affected files
