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.
