Companion Lite 0.1.18

Companion Lite 0.1.18 — a real, signed Windows installer.

A proper installer. Companion Lite now installs like a normal Windows app —
a Start Menu entry, a clean uninstall, no admin prompt — instead of a loose exe.
Under the hood it moved from a single packed file to a folder layout, which
starts faster and stops tripping antivirus "packer" heuristics.

Signed with a verified publisher. The installer and the app are code-signed,
so Windows shows Joel Andrew Chambers as the publisher instead of an
"unknown publisher" warning.

A note on first download: Windows SmartScreen may still say the file "isn't
commonly downloaded." That is reputation-based, not a signing problem — a brand
new file has no download history yet, and it clears on its own as more people
install the signed app. The signature is what makes that reputation stick to us
rather than resetting every build.

Auto-start is your choice. On first run it asks, once, whether to start with
Windows — never silently on — and you can change it any time from the tray menu.
Uninstalling removes it cleanly.

Values and capture behavior are unchanged from 0.1.17.
