[BUG][OPENCODE|DESKTOP] Can't used any `/commands` on DESKTOP, suspect `~/.opencode/` and `./.config/opencode` might conflicting on each other

Description

As the Title says "Can't used any /commands on DESKTOP, suspect ~/.opencode/ and ./.config/opencode might conflicting on each other".

For the past 2 months, I've been struggling to use the Opencode Desktop app anymore. The only major change I made was installing ECC and Caveman to improve my daily workflow.
Ever since then, I haven't been able to use Opencode's built-in slash commands (e.g. /init). They consistently fail with a "server error".
I already opened an issue in the Opencode repository, but with around 3.8K open issues, it seems like my report (and many others) has gone unnoticed.
What's strange is that Opencode CLI works perfectly. Every command runs without any issues. The problem only exists in the Desktop application.
After digging into it, I noticed something interesting:
The default Opencode harness is stored in ~/.config/opencode, and both the CLI and Desktop versions seem to use it without problems.
However, when installing certain tools, plugins, or harnesses (such as ECC/Caveman), they appear to be installed under ~/.opencode instead of ~/.config/opencode.
I'm starting to suspect that this mismatch between the two directories might be causing the Desktop app to fail while the CLI continues to work normally.
Has anyone experienced the same issue or figured out what's causing it? If you've found a workaround or fix, I'd really appreciate hearing about it.
