feat(baoyu-post-to-x): add Chrome Computer Use as preferred execution mode

In Codex, prefer the bundled Chrome Computer Use path for all X UI
actions (compose, article, quote, video). CDP scripts become a fallback
when Computer Use is unavailable or explicitly not requested.

+
+When running inside Codex, first detect whether Chrome Computer Use is enabled:
+
+1. If Computer Use tools are already visible, call `get_app_state` for `Google Chrome`.
+2. If not, use `tool_search` for `computer-use get_app_state click press_key drag scroll Google Chrome`, then call `get_app_state`.
+3. If `get_app_state` succeeds, use the user's real Chrome with Computer Use for all X UI actions.
+4. Use CDP scripts only when Computer Use is unavailable or explicitly requested.
+
+If the user explicitly asks for Chrome Computer Use, do not use Playwright, the in-app Browser, or CDP without approval.

+The `x-browser.ts` script is the CDP fallback. It uses Chrome DevTools Protocol (CDP) to:
 1. Launch real Chrome (not Playwright) with `--disable-blink-features=AutomationControlled`
 2. Use persistent profile directory for saved login sessions
 3. Interact with X via CDP commands (Runtime.evaluate, Input.dispatchKeyEvent)
