Subject: [PATCH] fix(doctor): detect browsers installed via Nix, Home Manager,
 or PATH
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

chromeBinary() only probed legacy install paths (/Applications and
/usr/bin), so on machines where the browser is installed declaratively
(nix-darwin / Home Manager), Doctor reported the Interceptor capability
as 'broken — no Chrome/Brave/Chromium binary found' even though Chrome
was installed and on PATH.

Add the '/Applications/Nix Apps/' locations and fall back to a PATH
lookup via the existing which() helper. The fallback includes
'brave-browser', which also fixes the Linux-Brave false negative
reported in #1496 (item 3). No behavior change on machines where the
current candidate paths already match.
