Self-Update Feature

tx ships with a built-in self-update subcommand that pulls releases from GitHub. Install from source as usual—the command is available without extra feature flags:

cargo install --path .

Usage:

tx self-update             # update to the latest GitHub release
tx self-update --version v0.3.0

The release archive formats are aligned with cargo dist defaults (.tar.gz on Unix, .zip on Windows). Keep them in sync if you customize the distribution pipeline.
