test: add $, (output field separator) coverage for PRINT

[Koan-Bot]

What

Adds dedicated test coverage for $, (output field separator) handling in tied PRINT.

Why

The code fix for $, was merged as part of PR #199, but no dedicated tests existed for this behavior. This ensures the $, handling remains correct across future refactors.

Testing

6 test cases covering:

• Comma separator ($, = ",")
• Tab separator ($, = "\t")
• No separator (default undef)
• Single argument (no separator applied)
• Multi-character separator ($, = " | ")
• printf immunity (format handles args, not $,)

Rebased onto upstream/master

The $, code fix was merged as part of PR #199. This PR now contains only the test file (t/print_separators.t) with 6 dedicated tests for output field separator behavior.

Changes

• Removed code changes (already in master)
• Kept t/print_separators.t with 6 test cases
• Updated MANIFEST

Recreated: test: add $, (output field separator) coverage for PRINT

The original branch koan.atoomic/fix-print-ofs had diverged too far from master for a clean rebase. The feature has been reimplemented from scratch on top of current master.

Branch koan.atoomic/fix-print-ofs has been force-pushed with the recreation.
