Updates

Inside Skink: Ctrl+E, then help updates.

| Command | Does | |---|---| | skink --upgrade (or skink upgrade) | install the latest release in place | | skink --upgrade --check | only say whether a newer one exists | | skink --upgrade --version 0.1.0 | install that release (can downgrade) | | :upgrade | the same from inside, in the background |

With "updates": "notify" (the default) Skink checks GitHub at most once a day and says so in the status line. "auto" also installs, used from the next start; "off" never checks. SKINK_NO_UPDATE_CHECK=1 or CI turn the check off.

When GitHub's download links fail, the files come through the GitHub API instead (GH_TOKEN or GITHUB_TOKEN raises its rate limit), with the same checksum check. Installs owned by cargo, Homebrew, scoop or winget print that tool's command instead.

Release builds check a minisign signature on SHA256SUMS when the project signs its releases; SKINK_ALLOW_UNSIGNED=1 accepts older, unsigned ones.
