Keep touch Run captions under the examples row

[holgerd77]

Summary

• On phones, the Run tooltip was rendering as always-on inline copy in the Run column. Constraining it to the button width stacked one word per line; this puts the caption on a full-width row under examples + Run.
• Cypress: 412px visit with hover matchMedia stubbed off, then bounding-box checks so jsdom/default E2E cannot miss this again.

Test plan

• 8038 on a real phone: titled example select beside Run; hint (if shown) under the row, not a word column
• Narrow desktop window with a mouse: still no caption until hover
• cypress/e2e/widget-chrome-touch.cy.ts (included in npm run test:e2e)
