Retain Swift integer sanitizer qualification blockers

[DavidBakerEffendi]

The independent Swift integer-sanitizer control remains blocked: a local string-holding Int conforming to a module-local Numeric protocol is admitted as a command-injection barrier. Both that wrapper and a plain same-body wrapper also lack their expected flows, so the missing endpoint flows are not attributed solely to the barrier. The canonical sanitizer pair remains unrun.

Key Changes:

• Preregister and retain raw, real-integer, local numeric-lookalike, and plain-wrapper controls using the unchanged shipped flow configuration. Preserve the initial observational query compilation failure and the separately preregistered corrected diagnosis against the same hash-verified database.
• Retain resolved initializer owners, typed native barriers and base-declaration provenance. Add portable integrity and mutation tests that verify this blocked evidence without qualification promotion; keep the real parse initializer protocol-owned on Swift.FixedWidthInteger.

Touch Points:

• evidence/swift-sanitizer-qualification-v1/
• scripts/run-swift-sanitizer-control.py, scripts/trace-swift-sanitizer-control.py
• scripts/verify-swift-sanitizer-control.py, scripts/test-swift-sanitizer-control.py
• .github/workflows/ci.yml, .gitattributes, Swift qualification documentation

Validation: three test methods containing six semantic mutations and four copied-evidence mutations passed, including from a clean Git archive. Previous append, canonical source–sink, canonical entrypoint and pending integration verifiers passed; cargo fmt --check and diff checks passed. Extraction completed in 95.389 seconds; the corrected diagnostic queries completed in 11.443/10.925/10.293 seconds under the 60-second/2048 MiB request. Aggregate memory compliance and semantic completeness remain unproven. CI pending.

Refs #220 and #215. Both issues remain open; acceptance is incomplete. Append remains independently blocked. No full-corpus execution, scored activation, freeze, or publication.
