When the SQL tokenizer returns an error location that falls in the middle of a multi-byte UTF-8 character (e.g., Chinese, Japanese), byte_offset would not be at a char boundary, causing a panic at &sql[..byte_offset]. Use str::floor_char_boundary() to clamp the offset to the nearest valid char boundary before slicing. Fixes deepflowio#11791

When SQL obfuscation is enabled for MySQL or PostgreSQL and the captured SQL contains multi-byte UTF-8 characters (Chinese, Japanese, etc.), the deepflow-agent panics with an index-out-of-range error. The obfuscation code was using byte offsets instead of rune offsets when splitting multi-byte characters.
The fix converts the string to a rune slice before splitting, so multi-byte characters are handled correctly.
