Unsupported architecture for upgrade

Error message

Unsupported architecture for upgrade

What it means

Target-detection guard in the upgrade path: cfg!(target_arch) matched neither x86_64 nor aarch64 (e.g. riscv64, i686), so no release asset exists for this CPU architecture. Self-upgrade cannot map the current build to a downloadable artifact.

Solutions

1. Install a build for a supported architecture (x86_64 or aarch64) from the releases page
2. If on exotic hardware, build from source with cargo build --release

When it happens

Trigger: Thrown at src-rust/crates/cli/src/upgrade.rs:164 when the library encounters an invalid state.
