refactor(wizard): cut the no-ops about time estimates

refactor(wizard): cut the no-ops about time estimates Telling the agent not to give minutes, in a template that has no minutes, pays load to say nothing — and naming the banned behaviour makes it more available, not less. The absence does the work. - SKILL.md: drop the "never give a time estimate" paragraph and the "stage takes no duration" note; the example stage already shows it. - template.sh: drop the two comments about not printing minutes. - docs: drop the sentence about there being no estimate.

What happened

The code refactor involved deleting the "never give a time estimate" instruction from SKILL.md, along with comments in template.sh and documentation notes that were already covered by the code examples.

Why it matters

This cleanup improves code readability and maintainability by reducing confusion and clutter, allowing developers to focus on core functionality without misleading or repetitive instructions.
