Version resume compatibility and clean up dump simulators

[lynnswap]

Purpose

Use an embedded PrivateHeaderKit producer version as the resume compatibility boundary, and make default Simulator devices owned by one dump run so they are always cleaned up.

Changes

• Generate build version source automatically from release/source-install metadata or Git identity, including dirty-source fingerprints.
• Emit and validate the producer version in raw-dump diagnostics and shared-cache inventory payloads.
• Replace device UUID and prepared helper paths in the resume fingerprint with producer and selected runtime identity.
• Treat helper schema/version contract failures as run-wide infrastructure failures.
• Create one dedicated Simulator for implicit selection and delete its exact UDID after success, failure, Back, or cancellation; keep explicit --device simulators borrowed.
• Document the updated Simulator and resume behavior.

Testing

• swift test — 563 tests in 43 suites passed.
• iOS Simulator cross-compile: PrivateHeaderKitCore and PrivateHeaderKitCoreTests.
• watchOS Simulator cross-compile: PrivateHeaderKitCore, PrivateHeaderKitCoreTests, and privateheaderkit-sim-helper.
• scripts/test-release-scripts.sh.
• Branch-wide codex-review against origin/main — no actionable findings.
