 * Resolves the absolute path of the installed Obsidian executable on the host machine.
 *
 * Used by desktop transports (`CLI`, `CDP`) to auto-launch Obsidian when it is
 * not already running. Supports installer-based installs (e.g.
 * `%LOCALAPPDATA%\Programs\Obsidian\Obsidian.exe` on Windows,
 * `/Applications/Obsidian.app` on macOS) and `PATH`-based installs (e.g.
 * `scoop` shims on Windows, package manager installs on Linux).
 *
 * The path is verified to exist on disk before being returned. If Obsidian
 * cannot be located, a descriptive `Error` is thrown so the caller can surface
 * an actionable message instead of spawning a non-existent binary (which on
 * Windows causes `start` to show a `ShellExecute` dialog box rather than
 * failing with an exit code).
