Package agentspec resolves how to update an agent.

Package detect probes the environment to decide how each agent is installed: which package managers are present, what their global bin dirs and package lists contain, installed VS Code extensions, and the latest available versions.

Package runner runs external commands with consistent timeout, cancellation, and process-group handling.

Package ui renders the live terminal dashboard.

Package vercache persists the output of agent version commands between runs, keyed by the resolved binary's identity (path, size, mtime) plus the argv.

Package version holds the pure version parsing, formatting, and comparison helpers used to read agent `--version` output, registry "latest" lookups, and to decide whether an installed version is outdated.
