// OpenCode Plugin: Version Check (no-op)
//
// Suede does not run `deciduous update` (see AGENTS.md "Do not run
// `deciduous update`" note). The upstream `deciduous` tool's
// `update` subcommand regenerates `.opencode/`, `.claude/`, and
// `AGENTS.md` from its own defaults, which would silently overwrite
// the hand-edited integration files in this repo. We treat version
// upgrades as opt-in: install a new `deciduous` binary if you want
// new features, then *manually* reconcile any new files you want to
// pull in — never via `deciduous update`.
//
// This plugin used to phone crates.io once per 24h and prompt the
// user to upgrade + run `deciduous update`. It was rewritten as a
// no-op for the reason above. The first time it runs, it appends a
// single line to `.deciduous/plugin.log` so the no-op is observable
// to anyone reading the log.
