## Description

`tui-agent-activity` was merged to main (commit fe0008ee8 at 12:05). User has freshly-installed binary (Apr 26 15:15, hours after merge). raw_stream.jsonl files for live agents EXIST in `.wg/agents/<id>/` (e.g. agent-93 has 15 MB / 383 events). But the TUI '4: Log' view STILL displays 'no agent output yet'.

Conclusion: the merged fix doesn't actually surface the data. The agent that claimed done didn't verify against the live TUI rendering. Identical verification-failure pattern as wg-nex-native.

### Diagnose

The Log pane code (likely src/tui/log_pane.rs or similar — find via grep for 'no agent output yet' literal string in src/) needs to be inspected:
- Does it open the right path? (`.wg/agents/<id>/raw_stream.jsonl`)
- Does it parse the format produced by claude-handler?
- Does it iterate alive agents and render their streams?
- Does it auto-refresh when new lines arrive?

Repro is trivial: open wg tui in this exact repo, switch to '4: Log' tab, observe 'no agent output yet' even though raw_stream.jsonl files have content.

### Fix

Read the streams from `.wg/agents/<id>/raw_stream.jsonl` for in-progress agents (both worktree-isolated and inline). Render events in the Log pane. Auto-refresh as new lines arrive (file watch or short poll).

### Hard gate

Before claiming done:
1. Open wg tui in a repo where at least one agent is alive AND has written events to its raw_stream.jsonl.
2. Switch to '4: Log' tab.
3. Confirm events appear (tool calls, edits, output) — NOT 'no agent output yet'.
4. Spawn a new agent in another terminal (`wg add 'echo test'; wg publish ...`); confirm the new agent's events appear in the Log pane within a few seconds.
5. Capture screenshot OR screen-grep of the rendered Log pane content as evidence.

Without points 1-5 done literally, do not call `wg done`.

## Validation

- [ ] Failing test first: test_log_pane_renders_raw_stream_events_for_alive_agent (use a synthetic raw_stream.jsonl + assert pane content includes event text)
- [ ] Implementation: actually read + render the streams
- [ ] cargo build + cargo test pass with no regressions
- [ ] HARD GATE manual smoke: as specified above

• 2026-04-26T22:56:33.988725695+00:00 Investigating: I see render path calls load_log_pane + update_log_output but NOT update_log_stream_events. Suspected bug: stream events only update on fs_change/1s tick, not on every render. Writing a TestBackend test to reproduce.
• 2026-04-26T23:11:21.983913835+00:00 Root cause found: render-time lazy load in render.rs draw_panel_content for RightPanelTab::Log called load_log_pane() + update_log_output() but NOT update_log_stream_events(). Stream events therefore only populated on the slow tick / fs-change path, never on first draw. Fix: add app.update_log_stream_events() to the render lazy-load block.
