internal/replace
This package hosts the core building blocks for the renamer replace command. The modules are
organized as follows:
request.go— CLI input parsing, validation, and normalization of pattern/replacement data.parser.go— Helpers for token handling (quoting, deduplication, reporting).traversal.go— Bridges shared traversal utilities with replace-specific filtering logic.engine.go— Applies pattern replacements to candidate names and detects conflicts.preview.go/apply.go— Orchestrate preview output and apply/ledger integration (added later).summary.go— Aggregates match counts and conflict details for previews and ledger entries.
Tests will live alongside the package (unit) and in tests/contract + tests/integration.
