[Bug]: Bracketed paste control characters [200~ leaked into terminal on Ctrl+V #198

发生了什么？/ What happened?

When copying and pasting text into the Navop SSH terminal session using standard shortcuts (Cmd+C / Ctrl+C and Cmd+V / Ctrl+V), bracketed paste escape sequences fail to be properly handled or stripped.

As a result, unwanted literal characters such as [200~ (and trailing ~) are inserted directly into the remote command line prompt (e.g., cd [200~<command>~).

如何复现？/ How can we reproduce it?

Environment

• Software: Navop
• Version: 0.17.0
• Client OS: macOS Tahoe 26.6.2
• Remote Host OS: Ubuntu 26.04 LTS
• Remote Shell: bash

Steps to Reproduce

1. Open Navop 0.17.0 on macOS Tahoe 26.6.2.
2. Establish an SSH connection to a remote server running Ubuntu 26.04 LTS.
3. Copy any text from the terminal or an external editor.
4. Paste the clipboard contents into the terminal via shortcut (Ctrl+V / Cmd+V).
5. Observe the text injected into the prompt.

Expected Behavior

The pasted text should be clean and match the clipboard content without leaking terminal escape sequences ([200~ / ~).

Actual Behavior

The terminal input receives raw control sequence artifacts, causing commands or directory paths to fail:

root@host:~/flow# cd [200~verify_activity~
-bash: cd: [200~verify_activity~
