Native CLI omits coverage command required by gap-analysis

[kreneskyp]

Regression\n\nThe native Rust CLI does not expose the coverage command required by the installed gap-analysis workflow.\n\n### Exact command\n\n quoin coverage --scope /home/peter/dev/worktrees/quire-language-117-source-packages --json\n\n### Working directory\n\n /home/peter/dev/worktrees/quire-language-117-source-packages\n\n### Expected behavior\n\nRun coverage reconciliation over the explicit scope and emit the JSON report (unbacked rows, status lies, untracked tests, and totals), matching the previously available npm/TypeScript CLI behavior used by gap-analysis.\n\n### Actual behavior / full output\n\n › Error: command coverage not found\n ›\n › Usage: quoin [options]\n ›\n › Commands: advise, assurance, catalog, change-assurance, completeness,\n › config, discharge, evidence, graph, matrix, measurement, module, report,\n › review, semantic, sync, to-plan, update, validate, write\n ›\n › Run quoin --help for details.\n\n### Version\n\n quoin --version\n 0.23.1-86-gc721d71\n\n### OS / architecture\n\n Linux 6.18.33.2-microsoft-standard-WSL2 x86_64\n\n### Minimal reproducer\n\nFrom any repository with a spec directory (or an empty temporary directory), run:\n\n quoin coverage --scope . --json\n\nThe command dispatch fails before inspecting the repository. The installed gap-analysis SKILL.md explicitly requires this command in Step 2.\n\n### Migration context\n\nNative binary: /home/peter/.local/bin/quoin. Falling back to the retained npm implementation only for this missing command, as authorized by the migration owner.

Not a Quoin command regression. Reproduced against both the native binary and the retained npm CLI: neither exposes quoin coverage. The gap-analysis workflow must invoke the Quire engine command, quire coverage --scope <scope> --json; its documented procedure already uses that command. Closing as an incorrect command attribution, with no native fallback or Quoin route to add.

Still reproducible after the issue was closed.

• Exact command: quoin coverage --scope . --json
• Working directory: /home/peter/dev/worktrees/quire-language-117-source-packages
• Expected: coverage reconciliation JSON required by the installed gap-analysis workflow
• Actual/full output:

 ›   Error: command coverage not found
 ›
 ›   Usage: quoin <command> [options]
 ›
 ›   Commands: advise, assurance, catalog, change-assurance, completeness,
 ›   config, discharge, evidence, graph, matrix, measurement, module, report,
 ›   review, semantic, sync, to-plan, update, validate, write
 ›
 ›   Run `quoin <command> --help` for details.

• quoin --version: 0.23.1-87-gb3d02d4
• OS/arch: Linux 6.18.33.2-microsoft-standard-WSL2, x86_64
• Minimal reproducer: from any directory, run quoin coverage --scope . --json; dispatch fails before repository inspection.

The native binary remains /home/peter/.local/bin/quoin.
