Socials Studio v0.1.0-beta.4 — Linux Chrome detection fix

Linux Chrome detection fix

v0.1.0-beta.3's Linux installer could mistake Chromium for the Google Chrome that Socials
Studio actually requires: setup accepted chromium/chromium-browser as satisfying the Chrome
check, but onboarding's runtime check has never accepted Chromium -- so setup could report Chrome
as present, and onboarding would then refuse the very executable it found.

v0.1.0-beta.4 aligns installer detection with the actual onboarding requirement: both now
recognise exactly the same three real Google Chrome executable names on Linux (chrome,
google-chrome, google-chrome-stable). Chromium remains unsupported -- Socials Studio's
login and publishing design deliberately depends on real Chrome, not Chromium.

Windows and macOS application behaviour is unchanged by this release.

Testing status

• All three installer packages (Windows, macOS, Linux) passed automated build and smoke tests.
• The beta.3 Windows installer was human-tested successfully on a real Windows 11 machine.
  This newly built beta.4 binary has not yet received a separate human hardware test.
• Linux: installer mechanics tested on Ubuntu 24.04 x64; real Chrome/account publishing has
  not been tested through this package.
• macOS: automated CI runner test only -- no human hardware test has been received yet.

If you try this on macOS or Linux, please report how it went (or open an issue).
