fix(server): run OpenCode CLI commands sequentially

[t3dotgg]

OpenCode startup runs models --verbose, agent list, and debug skill at the same time. Every OpenCode CLI command opens the same shared SQLite database, so the concurrent runs fail with "database is locked" and the provider exits with OpenCode server exited before startup completed (code: 1). The one second retry does not reliably cover this, and a second session in the desktop app can hard fail until restart.

The fix runs the three inventory commands one at a time in both the initial pass and the retry pass. The retry stays as it was. A comment above the call explains the SQLite constraint.

Closes #9208

Approvability

Verdict: Would Approve

Macroscope's review found this PR approvable — This is a focused server bug fix that serializes three OpenCode CLI inventory commands and their retries to avoid shared SQLite lock failures. It changes scheduling within one existing path without introducing new capabilities, schemas, infrastructure, or sensitive behavior.
