/**
 * HTTP transport for the Premiere bridge.
 *
 * Used on Windows (where there's no osascript) and optionally on macOS when
 * the user has installed the gg-editor-premiere-panel extension.
 *
 * Two panel runtimes are supported, both speaking the same wire protocol:
 *
 *   - **CEP** (legacy)   ExtendScript backend. Works on Premiere 22+. Adobe
 *                        has confirmed CEP support ends September 2026.
 *   - **UXP** (modern)   `require("premierepro")` backend. Required for
 *                        Premiere Pro 25.6+; the only path that survives
 *                        beyond Sept 2026.
 *
 * Both panel variants expose:
 *   - GET  /health  → {ok, product, port, kind: "cep"|"uxp", version?}
 *   - POST /rpc     → body {method, params}, response {ok, result|error}
 *
 * The bridge stays runtime-agnostic; we just record `kind` from health for
 * surfacing in capability strings + error messages.
