Switches every install command to the short form on our own domain:

curl -fsSL https://shorebird.dev/install.sh | bash

irm https://shorebird.dev/install.ps1 | iex

Merge after shorebirdtech/website#429 is deployed. Until then these URLs return 404.

Those URLs 302 to the same scripts in shorebirdtech/install, so updating a script still needs no deploy. The old raw GitHub URLs keep working for existing CI configs.

• -L is required: without it curl gets the 302, exits 0 (-f only fails on 400 and above), and bash runs an empty body.
• --proto '=https' --tlsv1.2 is dropped. The URL is https and the only redirect is ours to GitHub over https; -fsSL is what Homebrew, Bun, Deno and uv publish.
• irm replaces iwr -UseBasicParsing: it returns the script text directly, and -UseBasicParsing does nothing on PowerShell 7.
• The get_install_command agent tool in Head.astro piped to sh; it now pipes to bash like the docs.

Also covers public/.well-known/agent-instructions.txt.

Reviewed, no findings.

• Every POSIX command is curl -fsSL https://shorebird.dev/install.sh | bash: 15 occurrences, including agent-instructions.txt, Head.astro and the Codemagic YAML. With -L the 302 is followed, and with -f a failure exits non-zero instead of piping an error page into bash.
• PowerShell uses irm … | iex, which follows redirects. The quotes nest correctly inside the Head.astro string, and switching | sh to | bash matches the script's shebang.
• No raw.githubusercontent.com/shorebirdtech/install URLs are left in src or public.
• shorebirdtech/website#429 is deployed: production /install.sh and /install.ps1 return 302, and curl -fsSL gets the real scripts.
• CI passes (build, spell-check, style-check, vale).
