feat: provider extensions and drop claude-code-router mode (#295)

* feat: add ReportOutputProvider for consumer-extended report artifacts

* fix: thread deliverablesSubdir through report assembly

* fix: produce structured report JSON on resume path

* fix: fail loud on structured report output provider errors

* feat: extend checkpoint provider and container DI for consumer-specific backends

* fix: pre-create .shannon overlay mount points on all platforms

* chore: drop claude-code-router mode

* fix: drop 'resets' keyword from spending-cap text patterns
