Constant MOUSE_ENABLE 

pub const MOUSE_ENABLE: &[u8] = b"\x1b[?1001l\x1b[?1003l\x1b[?1005l\x1b[?1015l\x1b[?1016l\x1b[?1000;1002;1006h\x1b[?1000h\x1b[?1002h\x1b[?1006h";

Enable SGR mouse reporting with mode-hygiene pre-reset:

• reset legacy/alternate encodings (1001/1003/1005/1015/1016)
• enable canonical SGR modes (1000 + 1002 + 1006)
• emit 1016l before 1006h so SGR mode remains active on terminals where trailing 1016l forces X10 fallback.

Enables:

• 1000: Normal mouse tracking
• 1002: Button event tracking (motion while pressed)
• 1006: SGR extended coordinates (supports > 223)
