Repair common JSON parse errors

A parser error is a location clue, not a reason to rewrite everything. Start at the named line and inspect the character immediately before it.

Checklist

  1. Read the line and column, then look one token earlier.
  2. Add a missing comma, quote, bracket, or brace; remove a trailing comma.
  3. Format again and validate before changing values.

Example and limit

Example: `{ "enabled": true "count": 2 }` needs a comma after `true`.
