docs(cli): update for Node.js environment (#23)

* docs(cli): update for Node.js environment

The npm bundle now targets Node.js (shebang #!/usr/bin/env node,
build --target node). Update CLI docs to reflect:

- Remove Bun shebang requirement note from installation
- Change global install from `bun add -g` to `npm install -g`
- Simplify one-off section to npx (no longer needs Bun on PATH)
- Add note that Node >= 18 is sufficient, Bun is optional
- Update description to match new tagline

* docs(cli): show all package managers, comment out Homebrew

- One-off section: npx / pnpx / bunx tabs
- Global install: npm / pnpm / yarn / bun tabs
- Comment out Homebrew section (not ready yet)
- Bun no longer a hard dependency, Node >= 18 is sufficient

Addresses CodeRabbit feedback on #23.

-The npm bundle uses a `#!/usr/bin/env bun` shebang, so you need Bun on your `PATH`. Install it with:
+## Global install
 
-```sh
-curl -fsSL https://bun.sh/install | bash
+For daily use, you can install globally so `photon` is always on your `PATH`:

 ## Standalone binary
 
 If you don't want any runtime dependency (e.g. CI environments), you can download a prebuilt binary directly. Replace `<os>` and `<arch>` with your platform:
