+ * Resolve the path to a Chromium browser's History SQLite file.
+ *
+ * Algorithm:
+ *  1. Read `Local State` JSON from the browser root dir; use `profile.last_used`
+ *     to pick the active profile directory.
+ *  2. If that profile has a History file → use it.
+ *  3. If Local State is missing or lacks the field → fall back to `Default/History`.
+ *  4. If Default doesn't exist either → scan subdirectories matching `Profile *`
+ *     and `Default`, returning the first one that contains a History file.
+ *  5. As a last resort, return the `Default/History` path (caller checks existence).
