* fix(setup): correct OpenCode skills install path in status message (#1381)
The log message reported ~/.config/opencode/skill/ (missing trailing s)
while the actual install path was already correct (skills/). Fixes the
misleading output so users see the real destination directory.
* test(setup): add OpenCode plural skills-path integration test (#1381)
Verifies that setup installs skills into ~/.config/opencode/skills/
(plural) and that the singular path does not exist.
