OpenCode truncation: cannot jump to matched messages that are not rendered

[bojackduy]

Problem

OpenCode's TUI only renders a limited window of conversation history. Older messages exist in the SQLite database but are not rendered in the session view. When Telescope finds a match in an older message and tries to jump to it, it cannot find the DOM node because it does not exist.

Root causes

• jumpToRenderedTarget (ui/render-target.ts:20-45): Polls the render tree recursively looking for the message by ID. If OpenCode truncated it, the node never appears → polling times out → user lands at the top of the session instead of the matched message.
• OpenCode behavior: The session view only renders a subset of messages (likely the last N). The rest are in the DB but not in the virtual DOM.

Suggested approach

• Investigate OpenCode's truncation threshold
• Options:
  • Send a command/key sequence to scroll up / load more before jumping
  • If OpenCode exposes an API to load a specific message range, use it
  • As a fallback: highlight the session name and suggest the user scroll up manually
  • Patch OpenCode to preserve the target ID and auto-scroll on render
