@claude-flow/watermark/web: call `await init()` before use

Error message

@claude-flow/watermark/web: call `await init()` before use

What it means

assertReady() in the wasm-bindgen web wrapper found _ready false: init() was never awaited (or failed) before calling a watermark API. Sentinel guard — the WASM module instance is missing, so any tournament/gumbel scheme call would dereference uninitialized exports.

Solutions

1. Ensure the module/bridge/plugin initialize() method has been called and awaited before invoking this operation.
2. Guard against calls made during startup: await the initialization promise or check the initialized flag and fail fast with a clear setup hint.
