## Problem

`agents list <session-id>` always returns empty results. The subagent directory path used in discovery is wrong.

## Root cause

`discover_agents_for_session(session_file)` in `src/parser/discovery.rs:198-205` does:

```rust
let parent = session_file.parent();          // ~/.claude/projects/<project-dir>/
let subagents_dir = parent.join("subagents"); // ~/.claude/projects/<project-dir>/subagents/
```

That directory never exists.

`discover_all_agents()` has the same bug: it iterates project dirs and looks at `proj_path.join("subagents")` directly — also wrong.

## Actual disk structure

Confirmed across multiple sessions in the live `~/.claude/projects/` dir:

```
~/.claude/projects/<project-dir>/
  <session-uuid>.jsonl            ← session file
  <session-uuid>/                 ← directory with same name as UUID (no .jsonl)
    subagents/
      agent-<id>.jsonl
      agent-<id>.meta.json
```

Example path that should work but currently returns empty:
`~/.claude/projects/.../def4776b-25a6-4eca-99e7-f222926c297a/subagents/agent-a8e741de240089eef.jsonl`

## Required fix

`discover_agents_for_session(session_file)` should construct:

```rust
let stem = session_file.file_stem().unwrap(); // "def4776b-...-f222926c297a"
let session_dir = session_file.parent().unwrap().join(stem);
let subagents_dir = session_dir.join("subagents");
```

`discover_all_agents()` must also be updated to walk UUID subdirectories inside each project dir instead of looking at `<project-dir>/subagents/` directly.

## Secondary issue

The existing unit tests in `src/commands/agents.rs` (`dump_with_real_agent_returns_ok`, `transcribe_with_real_agent_returns_ok`) create subagents at the old wrong path (`projects/subagents/`) and must be updated alongside the fix.

## Relevant files

- `src/parser/discovery.rs` — `discover_agents_for_session` (lines 198–205), `discover_all_agents` (lines 211–266), `collect_agents_in_dir`
- `src/commands/agents.rs` — integration tests

## Summary of Changes

- Fixed  in  to use  to derive the sibling  directory
- Fixed  to iterate UUID subdirectories inside each project dir and call  on each 
- Updated tests in  (, ) to create agent files at the correct path structure
