packslip plugin sources currently require a GitHub repositor

Error message

packslip plugin sources currently require a GitHub repository

What it means

Packslip source parsing (`PackslipSource::parse` in src/plugins/packslip.rs) only supports sources of the form `packslip:github.com/owner/repo[#version]` where the project is a GitHub repository known to the packslip model. If the string after `packslip:` is not a `github.com/...` path or is not a recognized repository, parsing fails with this message.

Solutions

1. Use the full GitHub repository path: `mise use packslip:github.com/owner/repo`.
2. Verify the repository actually publishes packslip release manifests (`mise ls-remote packslip:github.com/owner/repo`); if not, use `mise use github:owner/repo` or `aqua:owner/repo` instead.
3. Check for typos or org/rename changes in the repository path.

Example fix

// before
[tools]
mytool = "packslip:mytool"

// after
[tools]
mytool = "packslip:github.com/owner/mytool"

// validate before writing the spec
case "$src" in
  packslip:github.com/*/*) mise ls-remote "$src" >/dev/null || echo "unknown packslip repo: $src" ;;
  packslip:*) echo "packslip sources must be github.com/owner/repo: $src"; exit 1 ;;
esac

fn is_packslip_github_repo(src: &str) -> bool {
    src.strip_prefix("packslip:")
        .map(|p| p.starts_with("github.com/") && !p.starts_with("github.com//"))
        .unwrap_or(false)
}

When it happens

Trigger: A tool source string like `packslip:mytool`, `packslip:gitlab.com/owner/repo`, `packslip:github.com/owner/nonexistent`, or a typo'd/renamed repo passed via `mise use packslip:...`, a mise.toml `[tools]` entry, or the registry.

Common situations: Typing a bare tool name instead of the full github.com path; pointing at a repo that does not publish signed packslip manifests; vendor renamed/transferred the repository; confusing packslip with aqua/github source prefixes.
