Checked transformation sources

This suite reconstructs the motivating shape from PR #8597: decode an Array of 1,000 rows, each containing eleven pattern-checked string fields and one n field. The sibling fields match /^[a-z][a-z0-9]{1,15}$/, and the checked numeric source matches /^[0-9]{1,6}$/. Rows contain value0 through value999 and numeric strings 1 through 1000. Schemas, inputs and parsers are prepared outside the measured callback. Each operation decodes all 1,000 rows.

• digits validates the checked string without transforming it.
• checked-source converts the checked numeric string to a number.
• unchecked-source converts a plain string to a number.
• two-passes first validates all fields, then decodes the validated output with a transformations-only Struct.
• checked-template-target and unchecked-template-target convert the n field to a TemplateLiteral string prefixed with x-. They measure valid input through the parser fallback required to preserve template diagnostics.

Every worker validates the complete output before and after measuring. The comparison harness copies the same fixtures into both revisions and alternates base/head order in fresh Node processes.

These fixtures use repository sources. The PR's original figures used packed packages on Node 26.10, so compare relative changes rather than absolute times.
