[BUG] TUI Panic Leaves Terminal in Raw Mode

[olddev94]

Project

vgrep

Description

The interactive TUI in src/ui/search_tui.rs does not properly handle panics. If any code between enable_raw_mode() and disable_raw_mode() panics, the terminal will be left in raw mode, making it unusable until the user runs reset or opens a new terminal.

Error Message

After panic, terminal shows:
- No echo of typed characters
- No line editing
- Ctrl+C doesn't work properly
- Prompts not displayed correctly

Actual Behavior

If panic occurs:

1. Terminal left in raw mode
