Demo-friendly additions: scenario names, saved recipes, and a stable stats frame

[hallmansm]

First off — thank you for this simulator. I'm an agile coach using it to show teams and leadership why WIP limits and cross-skilling beat adding headcount, and it does that job beautifully. This branch grew out of running it in live demos; everything here exists to make those demos smoother.

What this adds

Scenario names. The stats columns are all titled by the workload string (e.g. dev: 1), so two runs with the same workload but different workers or WIP limits are hard to tell apart — especially five or six scenarios deep into a demo. An optional Name field ("WIP-limit 5", "2nd developer", "full stack"…) becomes the scenario's title in the stats comparison and the document title. Left blank, it falls back to the current behavior.

Saved recipes. Named scenarios are saved to localStorage and reappear in a Recipe dropdown — pick one and the whole form fills in. Re-running under the same name updates that recipe in place; a small × button deletes the selected recipe. Lets a presenter walk into a room with a prepared sequence ("Base Team → 2x People → WIP throttling → Cross-skilling") instead of retyping configs live.

A Clear button that resets runs and charts for the next audience while keeping saved recipes.

A stable stats frame. Large teams (4×/8×) produce dozens of worker-utilization rows that shoved the animation far down the page. The scenarios comparison now caps at a fixed height (a ~14-worker team fits without scrolling) and scrolls vertically inside its own frame — the board and charts below stay put regardless of team size.

Small fixes along the way: worker and skill names parse case-insensitively; the selected column's outline is no longer clipped by the sticky header; the stats titles wrap cleanly.

Notes

• All 140 unit tests pass.
• No behavior change when the Name field is left empty and no recipe is used.
• Happy to split this into smaller PRs if you'd prefer to take the name field alone — say the word.

Pushed two follow-up commits after using this in anger for a demo prep session: (1) the selected column's outline was being clipped by the overflow-auto scroll container, and long workload titles wrapped to two lines and misaligned the stat rows against the legend - fixed with internal padding and a one-line ellipsis title (full title available on hover); (2) worker/skill names are now accepted case-insensitively - typing Fullstack flagged the field invalid, and would have produced a worker with no skills. Happy to split the case-insensitivity commit into its own PR if you prefer smaller reviews.

One more, born from rehearsing an actual talk: saved recipes. Any run submitted with a Name is remembered (localStorage); a Recipe dropdown refills the whole form from any saved run, and a Clear button resets the page for a blank slate while recipes survive. Makes live comparisons typo-proof: pick, Run, talk. As before - happy to split any of these commits out into separate PRs if you'd rather review them piecemeal.
