Detailed Description

Renders diagnostic messages with source context and caret/tilde indicators, similar to clang/rustc output.

Example output:

error: Unexpected character
  --> test.svg:1:25
   |
 1 | <path d="M 100 100 h 2!" />
   |                         ^

For multi-character ranges, tildes indicate the span:

warning: Invalid paint server value
  --> line 4, col 12
   |
 4 | <path fill="url(#)"/>
   |             ^~~~~~
