fix: forward waitUntil through navigate so adapters can skip the load-event wait

[ngaurav]

Summary

Fixes #106.

Never-idle sites (e.g. zillow.com, which streams analytics requests indefinitely) never fire the browser load event, so every page.goto() timed out after 30s even though the document had rendered — zillow/rentals failed on every run.

• protocol.ts: add waitUntil?: 'load' | 'none' to BrowserRuntimeCommand
• page.ts: Page.goto forwards waitUntil in the navigate command (primary and stale-identity-retry paths)
• local-cloak/actions.ts: map 'none' to Playwright's 'commit'; default remains 'load', so behavior is unchanged unless an adapter opts in

Backward compatible in both directions: old daemons ignore the extra field; old CLIs never send it.

Testing

• npx tsc --noEmit clean
• npx vitest run src/browser/: 34 files, 460 tests pass (new provider test for the 'none' → 'commit' mapping; forwarding assertion added to the existing Page.goto test)
• End-to-end: with the repo daemon and a zillow adapter passing { waitUntil: 'none' }, webcmd zillow rentals "San Francisco, CA" --max-rent 5000 --min-beds 2 --pets --parking completes in ~11s; previously it burned two 30s load-event stalls and exceeded the 60s command budget

🟠 Maintainer review suggested — medium confidence

The automated review could not reach a fully supported conclusion.

Findings

1. SKILL — Adapters can now pass `{ waitUntil: 'none' }` to `Page.goto()` to skip waiting for the browser load event, mapping to Playwright's 'commit' state.
   • Changed: src/browser/page.ts
   • Evidence: async goto(url: string, options?: { waitUntil?: 'load' | 'none'; settleMs?: number }): Promise<void> {
   • Suggested update: skills/webcmd-adapter-author/SKILL.md
   • Why: The adapter authoring skill guide is not in the provided context, but it should document the new `waitUntil` option for `Page.goto` so developers writing adapters know how to handle never-idle sites.
