Module formatter 

Sage source code formatter.

Provides an opinionated, non-configurable formatter for Sage source code. Similar in spirit to gofmt and rustfmt.

Formatting Rules

• Indent with 4 spaces (no tabs)
• One blank line between top-level declarations
• Two blank lines before run statement
• Handler ordering: on start → on message → on error → on stop
• Binary operators with spaces either side
• Closing braces on their own line
• Spawn initializer fields: one per line if >2 fields, inline if ≤2
