hook adapter: verify OpenCode runtime in serve/desktop mode

[WaynezProg]

Status: ⏳ Pending serve/desktop runtime verification

OpenCode plugin installed at ~/.config/opencode/plugins/runlens-hooks.ts and registered in opencode.json.

Direct-call verified. Plugin loads without error in serve mode (confirmed via --print-logs).

Manual step needed: Use opencode serve or the desktop app, start an agent session, and verify session.created / agent.finished appear in hooks.jsonl.

Note: The run mode does not fire plugin hooks — only serve/desktop mode triggers event bus subscriptions.

Runtime verified ✓

Verified 2026-06-05 via opencode run on the RunLens project.

A single session produced all three event types in hooks.jsonl:

agent=opencode  event=SessionStart  raw_keys=[sessionID]
agent=opencode  event=PostToolUse   raw_keys=[sessionID, callID, tool, title]
agent=opencode  event=Stop          raw_keys=[sessionID, messageID, partID]

All events have correct cwd and git_repo. Plugin uses chat.message →
SessionStart, tool.execute.after → PostToolUse, experimental.text.complete → Stop.
