#10937: fix(browser): correct fallback path for bundled Chrome extension

## Summary - Fix the `resolveBundledExtensionRootDir()` fallback path from `../../assets/chrome-extension` to `../assets/chrome-extension` - The bundler (rollup) strips the directory walk-up loop, leaving only the fallback `return` statement - The original path `../../` is correct relative to `src/cli/` but wrong relative to `dist/` where the bundled code runs, causing `"Bundled Chrome extension is missing. Reinstall OpenClaw and try again."` errors on `npm install -g openclaw` ## Root Cause In `src/cli/browser-cli-extension.ts`, the function `resolveBundledExtensionRootDir()` has: 1. A `while` loop that walks up directories looking for `assets/chrome-extension/manifest.json` 2. A fallback: `return path.resolve(here, "../../assets/chrome-extension")` After bundling, the loop gets stripped, leaving only the fallback. Since the bundled output lives in `dist/` (one level deep), the correct relative path should be `../assets/chrome-extension` (up one level to project root), not `../../assets/chrome-extension` (up two levels, escaping the project root). ## Test plan - [ ] `npm install -g openclaw` on a clean machine - [ ] Run `openclaw browser extension install` — should succeed without "missing" error - [ ] Verify `~/.openclaw/browser/chrome-extension/manifest.json` exists - [ ] Existing tests in `browser-cli-extension.test.ts` still pass (the walk-up loop handles dev mode) <!-- greptile_comment --> <h2>Greptile Overview</h2> <h3>Greptile Summary</h3> - Updates `resolveBundledExtensionRootDir()`’s fallback path to point at the packaged `assets/chrome-extension` when running from `dist/`. - Addresses a production-only failure where bundling removes the directory-walk loop, leaving only the fallback return. - Ensures `openclaw browser extension install` can find the bundled Chrome extension after `npm install -g openclaw`. <h3>Confidence Score: 5/5</h3> - This PR is safe to merge with minimal risk. - Change is a targeted path correction for a known production packaging layout issue, with no broad behavioral impact beyond the bundled-extension fallback resolution. - No files require special attention <!-- greptile_other_comments_section --> _{(2/5) Greptile learns from your feedback when you react with thumbs up/down!} **Context used:** - Context from `dashboard` - CLAUDE.md ([source](https://app.greptile.com/review/custom-context?memory=fd949e91-5c3a-4ab5-90a1-cbe184fd6ce8)) - Context from `dashboard` - AGENTS.md ([source](https://app.greptile.com/review/custom-context?memory=0d0c8278-ef8e-4d6c-ab21-f5527e322f13)) <!-- /greptile_comment -->
