v4.1.11

Small browser-launch follow-up.

Brave is now recognized when you set:

{
  "customBrowser": "brave"
}

On macOS it opens Brave Browser directly. On Windows and Linux it now uses the normal Brave executable names and install locations before falling back to the system default.

I also added regression coverage so this doesn't silently fall back to Safari/default again.

Checked with:

• python3 -B -m unittest tests.test_regressions
• Python compile check for touched files
• git diff --check
