Bundled plugins

Drop a <name>/plugin.{ts,tsx} here that default-exports a HermesPlugin and it registers automatically at boot (vite glob in ../contrib/plugins.ts), with the same inventory + live enable/disable contract as runtime plugins.

Keep this tree for real shipped plugins (and the small authoring fixtures that dogfood the SDK). One-off demos that rebuild a core chrome piece 1:1 do not belong here — they double the UI and confuse Settings ▸ Plugins. Publish those in the companion hermes-example-plugins repo instead.

User- and agent-authored plugins load at runtime from $HERMES_HOME/desktop-plugins/<name>/plugin.js (the disk door) — see the hermes-desktop-plugins skill.
