Module install 

Install path helpers for doctor and packaging checks. Chrome cache discovery for one-shot launches (no download / no apt).

PRD: system Chrome/Chromium only — no embedded BrowserFetcher in MVP.

Workload

I/O-light sequential: few version directories under XDG browsers cache. Rayon would cost more than a handful of read_dir entries (PAR-71).

Functions

find_installed_chrome

Find a Chrome binary previously placed under the product browsers cache.

get_browsers_dir

Cache directory for optional pre-placed Chrome builds (XDG cache).
