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.

Publish Markdown articles to X Articles editor with rich text formatting and images.
## Mode Selection
In Codex, prefer **Chrome Computer Use** when available:
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 that succeeds, use the Computer Use workflow below.
4. Use the CDP script workflow only when Computer Use is unavailable or explicitly requested.
If the user explicitly asks for Chrome Computer Use, do not fall back to CDP, Playwright, or the in-app Browser without approval.

## Usage
### Chrome Computer Use (Codex Preferred)
Prepare the article HTML and image map:
```bash
${BUN_X} {baseDir}/scripts/md-to-html.ts article.md --save-html /tmp/x-article-body.html > /tmp/x-article.json
```
Copy the generated HTML as rich text:
```bash
${BUN_X} {baseDir}/scripts/copy-to-clipboard.ts html --file /tmp/x-article-body.html
```
Then use Codex Computer Use against `Google Chrome` for all X UI operations.

## Workflow
## Computer Use Workflow (Preferred in Codex)
1. **Detect Computer Use**: call `get_app_state` for `Google Chrome`; use `tool_search` first if the tools are not visible.
2. **Parse Markdown**: run `md-to-html.ts --save-html /tmp/x-article-body.html > /tmp/x-article.json`.
3. **Read the map**: use `/tmp/x-article.json` for `title`, `coverImage`, and `contentImages`.
4. **Open X Articles**: use Chrome Computer Use to navigate to `https://x.com/compose/articles`.
5. **Create Draft**: click the create/write button if needed, or open the target draft.
6. **Upload Cover**: if `coverImage` exists, use Chrome's visible upload/file picker UI. If the file picker cannot be operated reliably, stop and ask for help rather than switching to CDP silently.
7. **Fill Title**: type the title into the title field.
8. **Paste Content**:
- Run `copy-to-clipboard.ts html --file /tmp/x-article-body.html`.
- Click the article body.
- Press `super+v` on macOS or `control+v` on Windows/Linux with Computer Use.
9. **Insert Images**: for each `contentImages` item in placeholder order:
- Run `copy-to-clipboard.ts image <localPath>`.
- Select the exact placeholder text (`XIMGPH_N`) in the editor.
- Press `super+v`/`control+v` with Computer Use.
- Wait for X to finish uploading media.
- If `XIMGPH_N` remains above the inserted image, reselect that exact text and press `BackSpace`.
- Do not press `BackSpace` unless the Computer Use state confirms the selected text is exactly the placeholder.
10. **Verify**:
- Inspect the Computer Use state for `XIMGPH_` residue.
- Confirm the expected number of image blocks is visible.
- Open Preview and verify title, cover, body, links, and images.
11. **Publish Safety**: ask the user for explicit final confirmation before clicking `Publish`.

2. Use persistent profile directory for saved login sessions
