## Problem

The TUI session list is always empty. `run_tui()` in `src/tui/run.rs` creates `AppState::new()` (which has `sessions: Vec::new()`) and enters the event loop without ever loading sessions from disk.

## Root cause

`discover_sessions()` in `src/parser/discovery.rs` is never called from the TUI startup path. The session list screen renders from `state.sessions` which stays empty forever.

## Fix

Before entering the event loop in `run_tui()`, call `discover_sessions()` and convert each `SessionRef` into a `SessionListItem`, then populate `state.sessions`.

### SessionRef → SessionListItem mapping
- `short_id` = first 8 chars of `session_id`
- `full_id` = `session_id`
- `date` = `modified_at.format("%Y-%m-%d %H:%M:%S")`
- `project` = `project_path.unwrap_or_default()`
- `model` = `""` (leave empty — would require parsing JSONL)
- `msg_count` = 0 (leave as 0 for now)
- `agent_count` = call `discover_agents_for_session(&session_ref.file_path).map(|v| v.len()).unwrap_or(0)`

Sort by `modified_at` descending (most recent first).

### Error handling
If `discover_sessions()` fails, start with an empty list (don't crash). Log the error to stderr before entering the alternate screen, or silently ignore.

## Relevant files
- `src/tui/run.rs` — `run_tui()` function, add session loading before the event loop
- `src/parser/discovery.rs` — `discover_sessions()` and `discover_agents_for_session()`
- `src/tui/state.rs` — `SessionListItem` struct

## Summary of Changes\n\nIn run_tui(), before the event loop: call discover_sessions() (silently empty on error), sort by modified_at descending, map each SessionRef to SessionListItem (short_id=8 chars, full_id, date=formatted timestamp, project=cwd, model/msg_count=empty/0, agent_count from discover_agents_for_session). Assign to state.sessions.
