fix(cli): prevent Ctrl+F from leaking to PTY as ^F artifact

Browse source 
When toggling shell focus mode with Ctrl+F, the raw control character
was being forwarded to the PTY, causing a ^F artifact to appear in the
shell. This fix intercepts the Ctrl+F keypress before it reaches the
PTY when it's used for focus mode toggling.

Fixes #2236
