/**
* `plugin_state` table — scoped key-value storage for plugin workers.
*
* Each row stores a single JSON value identified by
* `(plugin_id, scope_kind, scope_id, namespace, state_key)`. Plugins use
* this table through `ctx.state.get()`, `ctx.state.set()`, and
* `ctx.state.delete()` in the SDK.
*
* Scope kinds determine the granularity of isolation:
* - `instance` — one value shared across the whole Paperclip instance
* - `company` — one value per company
* - `project` — one value per project
* - `project_workspace` — one value per project workspace
* - `agent` — one value per agent
* - `issue` — one value per issue
* - `goal` — one value per goal
* - `run` — one value per agent run
*
* The `namespace` column defaults to `"default"` and can be used to
* logically group keys without polluting the root namespace.
*
* @see PLUGIN_SPEC.md §21.3 — `plugin_state`
