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.

 A **wizard** is a bash script that walks a human, step by step, through a manual procedure that's tedious to do by hand and tedious to re-explain to an AI every time. It opens each URL, says exactly what to click and copy, captures the values, writes them where they belong (`.env`, GitHub secrets), confirms at every stage, and shows how many stages are left. It might configure third-party services, run a one-off migration, or move the project from one state to another.
 
-**Never give a time estimate.** No minutes in the script, in the stage headers, or in what you tell the user — not for a stage, not for the wizard as a whole. Progress is measured in stages only.
-
 The delightful UX is already solved by [template.sh](template.sh) — stage-by-stage progress, confirmation gates, cross-platform URL opening (including WSL), hidden secret entry, idempotent `.env` upserts, `gh secret`/`gh variable` writes, and a closing summary. **Your job is only to scope the procedure and author its stages.** The library above the `STAGES` marker is identical in every wizard; that consistency is the point — never hand-edit it.
 
 A wizard is ephemeral by default — built for one run, saved to a scratch or `scripts/` path, deleted when the job's done. Commit it only when the user wants a repeatable setup path that should live in the repo.

-Copy `template.sh` to the target path. Replace the example stage with one `stage` per step, in dependency order. Use the library helpers — `stage`, `say`/`step`, `open_url`, `ask`/`ask_secret`, `write_env`, `set_secret`/`set_var`, `pause`/`confirm` — and set `TOTAL_STAGES` to the number of stages you wrote (this drives the progress display).

 Hold the bar the template sets: open the URL before asking for its value, use `ask_secret` for anything secret, `write_env` every persisted value, `set_secret` only the values CI actually needs, and `confirm` before any irreversible action. Each `stage` clears the screen so only the current step is visible — keep a stage to one focused task so nothing the human needs scrolls away. Don't touch the library above the marker.
