Subject: [PATCH] fix: disable SGR mouse tracking on exit to prevent ASCII
 codes

When users press CTRL+C in OpenCode TUI, the application exits without
properly disabling mouse causes the terminal to
continue tracking modes. This displaying SGR mouse tracking codes as ASCII strings when moving
the mouse.

This fix sends comprehensive mouse tracking disable escape sequences
before destroying the renderer, covering all common mouse tracking
protocols: basic, button events, SGR, SGR 1006, URXVT, and all motion
tracking modes.
