Introduce a reusable ExternalLink component that standardizes how we render external anchors across the site. It detects external HTTP(S) URLs (including protocol-relative //…), opens them in a new tab, and adds rel="noopener noreferrer" to prevent tab-nabbing. Internal, relative, in-page (#…) and scheme links (mailto:, tel:, blob:, data:) are treated as internal and keep default behavior.

Add a reusable ExternalLink component and adopt it in ecosystem cards to standardize outbound links. External HTTP(S) URLs open in a new tab with rel="noopener noreferrer". Internal/relative/scheme links keep default behavior.

Replaced raw anchors with ExternalLink to standardize external link behavior across ecosystem cards.
Avoids duplication of target="_blank"/rel="noopener noreferrer" and centralizes logic for internal vs external domains.
No visual changes expected.

Removed commented-out code and unused keyframes from Tailwind configuration.

Removed max description length limit and updated display logic.

Removed line-clamp class from Text component in Card.

Refactor scrollbar-gutter utility definition and add line-clamp utility.
