/**
 * Shared filter parser for CLI commands.
 *
 * Parses --filter strings in `field:operator:value` format into the API's
 * `{ field: { operator, value } }` body format.
 *
 * Syntax:  field:operator:value
 *   - field::value        → exact match (empty operator)
 *   - field:gt:value      → greater than
 *   - field:in:a,b,c      → value in list
 *   - field:isnull:true    → null check
 *
 * Numeric values are auto-detected and converted.
 * Multiple --filter flags are merged into a single filters object.
