Bug: opencode launch can return stopped session with no peekable logs

[c-h-]

What happened

agentctl launch opencode returned Launched session ed204dc4, but the session immediately showed Status: stopped, agentctl peek ed204dc4 -n 80 returned Session not found: ed204dc4, and no code changes were made in the target worktree.

What was expected

The launch should create a runnable session with inspectable logs/output, or at minimum surface a concrete failure reason instead of a stopped session with no peekable transcript.

How to reproduce

Run from a mono worktree:

agentctl launch opencode \
  --callback-session "agent:kindo:orgloop:github:pr:8745" \
  --callback-agent "kindo" \
  --cwd /Users/ms/code/mono-conversation-compaction \
  -p "Address PR #8745 review feedback ..."

agentctl status ed204dc4
agentctl peek ed204dc4 -n 80

Observed:

• launch prints a session id
• status reports stopped
• peek says Session not found

Workaround

Handled the fix directly in the worktree instead of relying on agentctl.

Environment

• agentctl: 1.9.0
• OS: macOS Darwin 25.2.0 arm64
• Working dir: /Users/ms/code/mono-conversation-compaction
• Adapter: opencode
