## Objective

Introduce an owned `RenderSubmissionSink` facade with minimal typed submission errors.

## Background

`DEC-0032` requires render publication to move away from `HardwareBridge` and to accept owned `RenderSubmission` values so the contract is compatible with async handoff.

## Scope

### Included

- Define `RenderSubmissionSink`.
- Define minimal `RenderSubmitError`.
- Implement the facade for the current local driver path.

### Excluded

- Do not migrate all publication call sites yet.
- Do not spawn a render worker.
- Do not remove `HardwareBridge::publish_render_submission`.

## Execution Steps

### Step 1 - Define sink and error

**What:** Add `RenderSubmissionSink` and `RenderSubmitError`.
**How:** `submit_render_submission(&mut self, submission: RenderSubmission) -> Result<(), RenderSubmitError>`.
**File(s):** `crates/console/prometeu-hal/src/platform.rs` or a render-specific HAL module.

### Step 2 - Implement local sink

**What:** Implement the sink for the current local driver implementation.
**How:** Adapt owned submission to the existing local `Hardware` publication path.
**File(s):** `crates/console/prometeu-drivers/src/hardware.rs`.

### Step 3 - Add tests

**What:** Prove owned submission is consumed by the local sink.
**How:** Add driver test using `RenderSubmission::game2d` and `RenderSubmission::shell_ui`.
**File(s):** `crates/console/prometeu-drivers/src/hardware.rs` or platform test module.

## Test Requirements

### Unit Tests

- Local sink accepts owned Game2D and ShellUi submissions.
- Error type is constructible and debuggable.

### Integration Tests

- `cargo test -p prometeu-hal -p prometeu-drivers`.

### Manual Verification

- Confirm the sink does not take `&RenderSubmission`.

## Acceptance Criteria

- [ ] `RenderSubmissionSink` takes owned `RenderSubmission`.
- [ ] Minimal typed error exists.
- [ ] Local driver implements the sink.
- [ ] Existing publication behavior remains intact.

## Dependencies

- `PLN-0098`.

## Risks

- Local paths may still need temporary borrow adaptation. Keep it internal to the implementation.
