docs: replace archived Roo Code with Zoo Code

Roo Code (RooCodeInc/Roo-Code) was archived May 15, 2026 and is
read-only. Its README points to Zoo Code (Zoo-Code-Org/Zoo-Code)
as the community-maintained fork.

Replaces the stale reference in the install docs rather than
listing both. CHANGELOG left untouched as historical record.
