fix: name extraction missing plural directory support (commands/, agents/) #7667

Description

Commit b9ef09a added glob pattern support for plural directory names (commands/, agents/), but did not update the name extraction logic accordingly.

This causes nested command/agent names to lose their prefix when using plural directory names.

Reproduction

When using OPENCODE_CONFIG_DIR pointing to a custom config directory with structure:

commands/
  email/
    digest.md

• Expected command name: email/digest
• Actual command name: digest (prefix lost)

Root Cause

In packages/opencode/src/config/config.ts:

1. The glob pattern correctly matches both singular and plural:

   const COMMAND_GLOB = new Bun.Glob("{command,commands}/**/*.md")

2. But the name extraction logic only checks for singular patterns:

   const patterns = ["/.opencode/command/", "/command/"]

3. When the path contains /commands/ (plural), no pattern matches, causing fallback to path.basename() which loses the directory prefix.

The same issue exists in loadAgent function.

Proposed Fix

Add plural patterns to the name extraction logic:

• For commands: add "/.opencode/commands/" and "/commands/"
• For agents: add "/.opencode/agents/" and "/agents/"

I have a fix ready and can submit a PR if this approach is approved.
