Adds docs/recipes.md, linked from the top of docs/tools.md. It covers the awkward rows from the #75 audit:

• print to PDF
• the Colors panel
• the Fonts panel
• install from a DMG, with the Gatekeeper prompt
• copy files between Finder folders
• Spotlight
• switching the input source
• the share sheet
• Control Center sliders
• a web form end to end, using feat: type into web text fields with key events so page scripts see the input #82's typing route

Format: each recipe is a tool sequence with the expected results, a final Verify step, and a Goes wrong list.

How it was checked: the tool behaviour is taken from the code: schemas, refusals, wait conditions, and the system state from #83. Nothing was run live, because the screen is locked. App-specific UI (titles, roles, which process owns a panel) is marked (unverified).

Not included: #77 (modifier clicks, key sequences) and #80 (media keys) aren't on main yet, so the recipes don't use them. Once they land, the Finder, keyboard and volume recipes can be shortened.
