Update README install examples to v1.1.0

[Copilot]

The README still pointed install commands at v1.0.2, which no longer matched the current tagged release. This updates the documented download and go install examples to use v1.1.0.

• README version refresh

  • Updated all release download URLs in /README.md from v1.0.2 to v1.1.0
  • Updated the Go install example to github.com/kitproj/kit@v1.1.0

• Installation examples aligned

  • Kept the existing install matrix intact for Linux/macOS and amd64/arm64
  • Changed only the versioned artifacts referenced by the examples

# For Linux (amd64)
sudo curl --fail --location --output /usr/local/bin/kit \
  https://github.com/kitproj/kit/releases/download/v1.1.0/kit_v1.1.0_linux_amd64

# For Go users
go install github.com/kitproj/kit@v1.1.0
