fix(copilot): update shared counter after collision detection

When collision detection in add_chat_messages_batch retries with a higher
sequence number, the actual persisted message count may differ from
len(session.messages). This commit ensures the shared counter
(saved_msg_count_ref) used by the streaming loop and long-running callback
stays synchronized with the actual DB state.

Changes:
- Modified add_chat_messages_batch to return tuple[list[ChatMessage], int]
  where the int is the final message count after collision resolution
- Updated _save_session_to_db and upsert_chat_session to propagate the
  final count up the call chain
- Updated all callers in sdk/service.py to use the returned count instead
  of len(session.messages) when updating saved_msg_count_ref
- Updated all other callers in service.py and tests to handle tuple return

-  These files are **ephemeral** — they exist only for the current session.
-- **Persistent storage**: Use `write_workspace_file` / `read_workspace_file`
-  for files that should persist across sessions (stored in cloud storage).
-- Long-running tools (create_agent, edit_agent, etc.) are handled
-  asynchronously.  You will receive an immediate response; the actual result
-  is delivered to the user via a background stream.
