Collapse hamburger menue

[shrinkray]

• Updated src/components/Header.astro to remove flex from the nav { ... } CSS rule.
• Updated the toggle script to:

open: remove hidden and add flex
close: add hidden and remove flex

[Copilot]

Pull request overview

Updates the header’s mobile navigation behavior so the hamburger menu properly collapses/expands by using Tailwind’s hidden/flex utilities instead of the project’s display-none helper class.

Changes:

• Switch header nav default mobile state to hidden (while keeping sm:flex for desktop).
• Update the hamburger toggle script to add/remove hidden and flex appropriately, and fix the #second-line selector typo.
• Bump caniuse-lite in package-lock.json.
