The /highlights command returns "No matching commands" after upgrading to v2.1.1 #57608

Description

1. Common Issue

After upgrading OpenCode from v2.1.0 to v2.1.1, the /highlights slash command is no longer recognized. In the TUI, typing /highlights returns a "No matching commands" error. This is a regression from v2.1.0, where the command worked correctly and was displayed in the autocomplete dropdown (as shown in the screenshots below).

2. Environment

• OS: Windows 11 (x64) & Ubuntu 24.04 LTS
• OpenCode Version: v2.1.1 (upgraded from v2.1.0)
• Installation Method: npm (global)

3. Platform Difference

While the core issue (/highlights command missing) is reproducible on both Windows 11 and Ubuntu 24.04, there is a platform-specific difference during the upgrade process:

• Windows 11: Running npm update -g triggers an EPERM warning during cleanup. It fails to unlink the old opencode.exe file, which may indicate a file lock or permission issue during the upgrade:

  npm warn cleanup Failed to remove some directories [
  npm warn cleanup   'D:\\npm-global\\node_modules\\@opencode\\.cli-xqxTodHT',
  npm warn cleanup   ...
  npm warn cleanup     [Error: EPERM: operation not permitted, unlink '...\\opencode.exe']
  npm warn cleanup ]

• Ubuntu 24.04: The npm update -g process completes without any warnings or permission errors. However, the /highlights command is still missing, indicating that the issue is not solely caused by the Windows file lock.

Screenshots & Logs

• v2.1.0 (Working): /highlights is available and displayed in the autocomplete list.
• v2.1.1 (Failing): Typing /highlights shows "No matching commands".
• Windows EPERM Log: Attached above.

Additional Context

The /highlights command was introduced in PR #54969. Given it's a stable release, it should be present. The fact that it's missing on both platforms suggests a potential build issue (missing embedded data) or a TUI autocomplete logic bug in v2.1.1.

OpenCode version

TUI 2.1.1

Steps to reproduce

1. Install OpenCode v2.1.0 globally via npm:

   npm install -g [email protected]

2. Open the OpenCode TUI and verify the command is available by typing /high. The /highlights command appears in the autocomplete list and works as expected.
3. Upgrade to OpenCode v2.1.1 using the global update command:

   npm update -g

   (Note: On Windows 11, this step throws an EPERM warning during cleanup, but the installation still completes. On Ubuntu 24.04, it completes without warnings.)
4. Open the OpenCode TUI again.
5. Type /highlights in the input field and press Enter.
6. Observe that the TUI displays a "No matching commands" message, and the command cannot be executed.
