Test executor and coder-agent tasks

task_id: ses_3acd78430ffe6Xg0st91Otbjxq (for resuming to continue this task if needed)

<task_result>
## Reasoning
After analyzing the Keyz OCaml repository, I found several test files with varying levels of completeness. The most promising candidate for implementation by an executor is the `test_simple.ml` file, which contains a basic tree navigation test but lacks proper assertions and comprehensive test coverage.

The `test_simple.ml` file currently has:
- Basic tree structure setup
- Navigation functions (`move_selection`, `toggle_expanded`)
- Print-based output instead of assertions
- No error case testing
- No boundary condition testing

This makes it an ideal candidate for an executor to enhance with proper test assertions and comprehensive coverage.

## Actions
1. Identified `test_simple.ml` as the primary candidate for enhancement
2. Found it lacks proper assertions and comprehensive test coverage
3. Determined it needs error case and boundary condition testing

## Next
The executor should implement proper test assertions and comprehensive coverage for the tree navigation functionality in `test_simple.ml`.

<task_result>
Based on my analysis, I've identified a **missing test case** for the `copy_password` function in `pass.ml`. The current tests don't cover the clipboard functionality, which is a critical security feature.

## Proposed Test: `test_clipboard.ml`

**File path:** `/home/jm/data/code/toki/test_build/test_clipboard.ml`

### Test Design

**Test case:** Verify password copying to clipboard with mock process manager

**Test inputs:**
- Mock entry: `{ name = "test"; path = ["test.gpg"]; is_dir = false }`
- Mock process manager that intercepts clipboard commands
- Mock `pass show` command returning "password123"

**Expected outputs/assertions:**
1. `wl-copy --paste-once` is called with password on Wayland
2. Falls back to `pass show --clip` on non-Wayland or missing `wl-copy`
3. Returns `Ok "test"` on success
4. Returns `Error` on process failure
5. Handles both Wayland and non-Wayland environments

### Implementation Steps

1. Create mock process manager that intercepts `Eio.Process.run`
2. Test Wayland path with `wl-copy --paste-once`
3. Test fallback path with `pass show --clip`
4. Test error handling scenarios
5. Verify proper return values

### Verification Commands

```bash
opam exec -- dune exec test_clipboard
```

### Proposed Patch Sketch

```ocaml
(* test_clipboard.ml *)
open Eio.Std

type mock_entry = {
  name : string;
  path : string list;
  is_dir : bool;
}

let mock_entry = { name = "test"; path = ["test.gpg"]; is_dir = false }
