Link Migrator

Added

• Initial release of Link Migrator for Craft CMS 5.
• Plugin Store description covering the staged workflow, safety controls, supported link types, template checks, and CLI usage.
• Staged migration workflow from Verbb Hyper to Craft's native Link field: audit, prepare-fields, content, and finalize.
• Control Panel wizard with per-field workflow status (admin-only).
• CLI commands with dry-run support; write commands require --force=1.
• Fresh content reconciliation gating finalize — cutover is refused while any non-empty source value is unverified.
• Template mismatch scanner (migrate/mismatches) with a finalize acknowledgement gate.
• Resumable migration state keyed by source field UID, with JSON/log reports and optional per-element backups.
