jedarden 098283c197 docs(bf-68nl): verify stream-json reader join on all exit paths

Add verification note confirming that the stream-json reader thread is
properly joined on all exit paths (success, timeout, interrupted, child
exit, early error).

All exit paths in session.rs correctly:
- Send drain signal and join (success, early error)
- Drop handle and join (timeout, interrupted, child exit)

Tests pass (90 passed).

Verification of stream-json reader join on all exit paths

Task (bf-68nl)

Ensure the stream-json reader thread is properly joined on all exit paths (success, timeout, interrupted, error).

Verification Status: COMPLETE ✓

The stream-json reader join implementation is already present in src/session.rs on all exit paths:

Exit paths verified

Success path (FifoPayload) - Lines 442-446
- Sends drain signal: handle.drain_tx.send(())
- Joins thread: handle.join_handle.join()
Timeout path - Lines 404-407
- Drops handle without sending: drop(handle.drain_tx)
- Joins thread: handle.join_handle.join()
Interrupted path - Lines 469-472
- Drops handle without sending: drop(handle.drain_tx)
- Joins thread: handle.join_handle.join()
Child exit path - Lines 460-463
- Drops handle without sending: drop(handle.drain_tx)
- Joins thread: handle.join_handle.join()
Early error path (no transcript path) - Lines 425-428
- Sends drain signal: handle.drain_tx.send(())
- Joins thread: handle.join_handle.join()

Acceptance criteria met

✓ Drain signal and join on success path (FifoPayload)
✓ Drop-and-join on timeout path
✓ Drop-and-join on interrupted path
✓ Drop-and-join on child exit path
✓ All paths join the thread before returning
✓ Code compiles and tests pass (90 passed)

Implementation details

The design distinguishes between two types of exit paths:

Graceful exits (success, early error): Send drain signal () via channel to allow the reader thread to finish processing remaining output before exiting.
Immediate exits (timeout, interrupted, child exit): Drop the sender handle without sending, which causes the channel to close immediately and the reader thread exits without waiting for more data.

In both cases, join_handle.join() is called to wait for the thread to finish before proceeding.
