OpenCADStudio no longer bundles plugins — every add-on is an external
cdylib loaded from the plugins folder or installed via the marketplace.
- Remove the demo plugin and the in-tree ocs_example_plugin crate.
- Remove the inventory-based built-in registration path (PluginRegistration,
all_plugins, installed_manifests); registry now serves core ribbon tabs
plus loaded external plugins, and try_dispatch routes only to externals.
- Plugin Manager drops the 'compiled into this build' section; the
enable/disable toggle moves onto loaded external cards.
- Prune the now-dead HostSession/DocumentTab helpers and re-exports.
Part of the #100 extensibility epic (phase 2).

Plugins targeted the host's concrete HostSession type. Add a HostApi
trait in ocs_plugin_api behind an optional `host` feature (the only thing
that pulls acadrust, so the core crate stays dependency-free). HostSession
implements it and BuiltinPlugin::dispatch now takes `&mut dyn HostApi`, so
an out-of-tree add-on compiles against the contract crate alone. Per-tab
plugin state is reached through object-safe plugin_state* helpers.
Completes the phase-1 host-surface extraction in the #100 epic.

Plugins persisted domain data via the raw acadrust::xdata API with
boilerplate and no APPID registration. Add read_record / write_record /
remove_record keyed by entity handle; write_record replaces an existing
record for the same app and registers the application in the APPID table
so the data round-trips through DWG/DXF for other CAD apps.
