feat: add gumlet-video-element- #250

[mudit2108]

Add an HTMLMediaElement-compatible custom element backed by Gumlet Player.js, with React wrapper, Next.js demo, and release-please registration.

---

Note

Low Risk
Additive new package following existing embed-element patterns; risk is mainly third-party Player.js/CDN and iframe playback edge cases, covered by targeted tests.

Overview
Introduces gumlet-video-element (<gumlet-video>), a new embed player package that mirrors the repo’s other video custom elements: Gumlet embed URLs (play.gumlet.io/embed/...), an HTMLMediaElement-style API, and Player.js loaded from jsDelivr to drive an iframe in shadow DOM.

Notable behavior in the new implementation includes a config object (DRM, ads, start_high_res, etc.) merged into the embed URL, disable_player_controls when controls is absent (for Media Chrome), SSR hydration via data-config on the iframe and a src refresh so Player.js can handshake, and lifecycle handling for reconnect, invalid src, and loadComplete promises.

Also wires the package into release-please at 0.1.0, documents it in the root README, adds a Next.js demo page/nav entry, and includes TypeScript types, a demo index.html, and zora tests.
