Wayland clipboard copy doesn't populate primary clipboard selection

[mickalpine]

Description

When using opencode in Wayland environments with wl-clipboard, copying text via highlight selection or Ctrl+Y only populates the regular clipboard but not the primary clipboard. This prevents pasting to the host OS when using VMware Workstation, which only syncs the primary clipboard between guest and host.

Additional context:

• wl-clipboard version: 2.2.1
• In VMware Workstation, only the primary clipboard gets synced between guest and host OS
• The issue affects both the highlight-to-copy functionality and the Ctrl+Y explicit copy command

Proposed solution:
Add a configuration option to control clipboard behavior in Wayland environments:

{
  "clipboard": {
    "linux": {
      "enablePrimaryCopy": true
    }
  }
}

When enablePrimaryCopy is true, the Wayland copy method should execute both wl-copy and wl-copy --primary.

OpenCode version

v1.0.195

Steps to reproduce

1. Run opencode TUI in a Wayland environment (Ubuntu 24.04)
2. Highlight text and copy using Ctrl+Y or text selection
3. In a terminal, check clipboard contents:
   • wl-paste (regular clipboard) - should show the copied text ✓
   • wl-paste --primary (primary clipboard) - should show the copied text ✗
4. Try to paste using middle-click (primary clipboard) - fails
5. Try to paste using Ctrl+V (regular clipboard) - works

@rekram1-node I created a PR to solve this issue #6370

To enable primary clipboard copy it would be add to opencode config (default is false):

{
  "clipboard": {
    "linux": {
      "enablePrimaryCopy": true
    }
  }
}
