Users without brew/AUR/winget/Nix (e.g. Alpine-based distros, generic Linux ARM64) currently have to manually pick the right release asset, verify its checksum, extract it, and set up shell completion by hand. This adds a POSIX install script that detects OS/arch, downloads the matching release tarball, verifies its SHA-256 against the published checksums, installs the binary to ~/.local/bin (or $SURGE_INSTALL_DIR), and best-effort installs zsh/bash/fish completions. Tested end-to-end on postmarketOS (Alpine/musl) aarch64. Refs SurgeDM#646

Pin the installer to an immutable revision.
This command pipes mutable main content directly to sh. A repository compromise can execute commands before the release archive checksum runs. Use an immutable commit or release artifact in both docs/getting-started.md and scripts/install.sh:6.

Make the shasum fallback reachable.
need sha256sum calls die, which exits the shell. Therefore, need shasum never runs, and systems with only shasum cannot install the program.

Fail immediately on HTTP download errors.
Both release downloads omit -f. For a 404 or 5xx response, curl can return success and save the error body. The archive then reaches tar, which reports a misleading extraction error. Add -f to both commands.

Keep completion failures non-fatal.
When mkdir or a completion command fails, each && chain returns non-zero. install_completion propagates this status to the top-level case, and set -e exits the installer after the binary is installed. Handle each branch with if ...; then ...; fi or explicitly consume the failure.

Hey @hanthor I looked at the PR here are a few inputs
other than that the script looks good to me. Thanks for contributing. Let me know if you need help making these changes. |

Closes #646.
Problem
The install matrix in
docs/getting-started.mdonly covers brew/AUR/winget/scoop/choco/Nix. Anyone without one of those — including generic Linux and Alpine-based distros like postmarketOS on ARM64 — is told to just "download a release" and figure out the rest by hand: pick the rightGOOS/GOARCHasset name, download the checksums file, verify it, extract,chmod +x, place onPATH, and separately runsurge completion <shell>.What this adds
