Harness config 1.0.0-alpha.7

1.0.0-alpha.7 adds the orphaned managed output cleanup workflow for profile
switching and non-active projections while preserving local runtime edits by
default.

Orphaned Managed Outputs

• Adds orphan activation plan entries for existing target files that are not
  in the active projection but could still be produced by a non-active profile
  or target selection.
• Keeps orphaned managed outputs by default and adds --remove-orphans for
  explicit cleanup of unedited orphaned files whose bytes still match the
  non-active source projection.
• Preserves edited orphaned files, mutable outputs, genuinely unmanaged target
  entries, and target-output .harnessIgnore boundaries during orphan cleanup.
• Compares cleanup candidates against final target override bytes, including
  dotfile outputs such as .gitignore.

Docs And Tests

• Documents the standard, conformance, tooling, CLI, and website-ready spec
  behavior for orphaned managed outputs.
• Adds regression coverage for profile switching, overlapping active and
  non-active outputs, mutable orphan preservation, target-output ignore
  boundaries, and target override byte comparison.
