Adds a new docs page under Getting Started that links to the
heygen-com/hyperframes-launches repo — open-source HyperFrames
compositions behind HeyGen's product launch videos. Includes a brief
catalog of the 5 projects currently in there, framing on why these are
useful (multi-composition shape, real adapter mix, production-grade
timing), and the LFS-aware clone recipe.
Cross-linked from `docs/examples.mdx`'s Next Steps and from
`docs/community/adopters.mdx`.
Came from a Discord ask via blackNoir (forwarded by James) — users
landing on the docs want to see how the internal team builds their own
videos through HyperFrames; this surfaces that source in one click.
Mirrors the canonical ADOPTERS.md table at the repo root and adds a
Mintlify CardGroup for visual presentation. Logos are intentionally
optional — orgs can self-add via PR with just the table row, and
upgrade to a logo later.
Wires the page in under a new Community group in the nav.
