Format-specific CLI options

[alvinreal]

Description

Add format-specific flags to the CLI.

Options

• --csv-delimiter <char> (default: comma)
• --csv-no-header (input has no header row)
• --csv-header <fields> (explicit headers)
• --xml-root <name> (root element name for output)
• --xml-attr-prefix <prefix> (default: @)
• --yaml-multi (treat as multi-document)

TDD Tests

• --csv-delimiter "\t" reads TSV correctly
• --csv-no-header returns array of arrays
• --csv-header "a,b,c" overrides detected headers
• --xml-root items wraps output in <items>
• --xml-attr-prefix _ uses _id instead of @id
• --yaml-multi reads --- separated docs
• Options only apply to relevant formats (no error if unused)
