OpenCode follows XDG Base Directory spec and expects config at
~/.config/opencode/, not ~/.opencode/. This fix:
- Add getOpencodeGlobalDir() to detect correct path via:
- OPENCODE_CONFIG_DIR env var
- OPENCODE_CONFIG env var (uses dirname)
- XDG_CONFIG_HOME/opencode
- ~/.config/opencode (default)
- Use 'command/' (singular) instead of 'commands/' (plural)
- Use flat file structure: command/gsd-help.md instead of
commands/gsd/help.md (invoked as /gsd-help)
- Write permissions to ~/.config/opencode/opencode.json
- Update content conversion to replace ~/.claude with
~/.config/opencode and /gsd: with /gsd-
Fixes OpenCode installation which was previously installing to
~/.opencode/ where OpenCode couldn't find the commands.
