bug: apm init asks "Continue and overwrite?" three times on Windows CP950 terminals

[edenfunf]

Description

On Windows systems with a non-UTF-8 console encoding (CP950, CP936, CP932), running apm init in a project that already has an apm.yml shows the overwrite confirmation prompt three times before accepting the answer.

Steps to Reproduce

1. Set up a Windows machine with a CJK locale (e.g. Traditional Chinese, CP950)
2. Create an APM project: apm init my-project
3. Run apm init my-project a second time
4. Type n and press Enter

Actual Behaviour

[!] apm.yml already exists
Continue and overwrite? [y/n]: n
[!] apm.yml already exists
Continue and overwrite? [y/n]: n
Continue and overwrite? [y/n]: n
[i] Initialization cancelled.

Expected Behaviour

The prompt appears once and the command exits cleanly.

Root Cause

init.py uses Rich Confirm.ask() wrapped in a try/except that falls back to click.confirm(). On CP950 terminals, Rich fails to decode the input, retries internally, then raises an exception — at which point the except block calls click.confirm() again. The user is asked three times.

Environment

• OS: Windows 11, console code page CP950
• apm version: v0.8.11
