feat: support --prerelease in install scripts#35
Merged
Conversation
Add an opt-in --prerelease (install.sh) / -Prerelease (install.ps1) flag that installs the newest release overall, including prereleases, by resolving the version from the GitHub releases list endpoint instead of releases/latest. Default behavior is unchanged. Also documents the option in README.md and specs/install.md. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Summary
install.shandinstall.ps1always installed the latest stable release because both called the GitHub APIreleases/latestendpoint, which excludes prereleases. This adds an opt-in flag to install the latest prerelease.Changes
scripts/install.sh— adds an argument-parsing loop supporting--prereleaseand-h/--help(unknown args error out). When--prereleaseis set, resolves the version from/releases?per_page=1(newest release overall, including prereleases) instead of/releases/latest.scripts/install.ps1— adds a[switch]$Prerelease(single capital P, matching the PowerShell-AllowPrereleaseconvention). When set, fetches the releases list endpoint and takes the first entry.README.md— short> [!TIP]notes showing how to request a prerelease from each one-liner.specs/install.md— documents the prerelease option and which endpoint each mode uses.Default (no-flag) behavior is unchanged.
