Verify implementation matches OpenSpec change artifacts. Use when the user wants to validate that implementation is complete, correct, and coherent before archiving. Also use when the user says "openspec verify" or "opsx verify".

## From README

Verification Report: Summary | Dimension | Status | |--------------|------------------| | Completeness | X/Y tasks, N reqs| | Correctness | M/N reqs covered | | Coherence | Followed/Issues | In each Status cell, report the results of checks that ran and Not verified ( ) for every skipped check. If all checks in a dimension were skipped, start the cell with Not verified. Never score a skipped check as passing. Treat every not verified or partially verified check as skipped in the final assessment. Count only ADDED and MODIFIED requirements in N, and report REMOVED and RENAMED requirements separately (for example, "1 removal confirmed, 1 rename verified", or "1 removal not verified (baseline unavailable)"). For a change that only removes or renames requirements, the Correctness cell reads Not applicable (no ADDED or MODIFIED requirements).
