fix: Remove unconditional bell ring for auto-approved tool calls (cli-21)

[szmania]

Summary

This PR fixes an issue where notifications (bell rings) were being sent for every tool call in agent mode, even after the user had approved all tool calls with "(A)ll".

Problem

In agent mode, after a user approves all tool calls with "(A)ll", cecli continued to send a notification (ring a bell) for every subsequent tool call that was automatically approved. This was annoying and unnecessary.

Root Cause

The _print_tool_call_info method in cecli/coders/base_coder.py unconditionally called self.io.ring_bell() before checking if user confirmation was actually required. The confirmation check itself (io.confirm_ask) is smart enough not to prompt (and thus not to notify) if an "all" preference is already registered, but the bell had already been rung.

Solution

Removed the unconditional self.io.ring_bell() call from the _print_tool_call_info method. The bell/notification is already correctly handled within the io.confirm_ask method, which is called right after _print_tool_call_info. This ensures the notification only triggers when the user is actually being prompted for confirmation.

Changes

• cecli/coders/base_coder.py: Removed self.io.ring_bell() from _print_tool_call_info method

Testing

User tested manually in agent mode:

1. Run cecli in agent mode
2. Issue a prompt that results in multiple tool calls
3. When prompted to "Run tools?", respond with "(A)ll"
4. Observe that subsequent, automatically-approved tool calls do not produce notifications
