docs: add multi-package-manager install examples to README

[Copilot]

The README installation section only showed an npm command. This expands it to cover all common package managers using the correct scoped package name.

Changes

• README.md: Expanded the Installation section with copy-paste commands for npm, pnpm, yarn, and bun

npm install @primajin/gyros
# or
pnpm add @primajin/gyros
# or
yarn add @primajin/gyros
# or
bun add @primajin/gyros
