Subject: [PATCH 1/2] fix: respect XDG base directory env vars for config and
 log paths

Config loader now checks XDG_CONFIG_HOME before falling back to
~/.config/opencode. Logger now uses XDG_DATA_HOME (defaulting to
~/.local/share) for log storage, which is where runtime data belongs
per the XDG Base Directory Specification.

No behavior change for users with default (unset) XDG paths.

Subject: [PATCH 2/2] fix: respect XDG_DATA_HOME in state persistence storage
 path

STORAGE_DIR in persistence.ts also hardcoded ~/.local/share instead of
checking XDG_DATA_HOME. Same pattern as the logger fix.
