refactor: remove test-only seams, dead option fields, and duplicate tests

[thymikee]

Summary

Production code reachable only from tests, option fields no caller sets, and tests that restated a sibling:

• DaemonError is now an alias of NormalizedError (field-for-field identical; wire ledger ack in the final gates commit).
• host-kit: one override-path resolver behind the executable and file variants, the canceled-command wrapper inlined, and the abort-aware sleep exported from retry instead of a second module.
• provision-kit drops the downloadTimeoutMs option no caller supplies; Android observation reads blocking dialogs through app-parsers instead of a verbatim copy.
• Deleted shutdownSimulator, providerDeviceAdmission(), CoordinateGesturePayload, getCloseShutdown, prefixItems, and selectMaestroSnapshotMatches: each had zero production references.
• isLikelyStaleSnapshotDrop is imported from capture-kit instead of duplicated; CheckId derives from ALL_CHECKS instead of a second 59-member list.
• Removed tests whose owner remains: a byte-identical plan-validator case, idle-reap and surface-signature cases implied by a tolerance test, a perf positional case subsumed by the case-insensitive one, interactor-catalog subsets of the seven-operation test, hint regexes duplicated by exact pins, a stub-client clipboard case covered through the real CLI, catalog and lockfile tests re-spelling their siblings, an output-economy expectation computed by the helper under test, and a zip fixture nothing imports. The never-run integration-progress-model.test.ts is now wired into check:affected:test.

Validation

Tested at 12b9b97: pnpm check:affected --run passed (format, lint, typecheck, daemon-wire-compat, related unit tests, check-affected and mutation node tests, output-economy project). No device run applies.

This PR is ready at 12b9b97. The removed seams, dead option fields and duplicate tests look right to me, and I found nothing that needs a change.

Not blocking: wiring scripts/integration-progress-model.test.ts into check:affected:test in package.json (https://github.com/callstack/agent-device/blob/12b9b97/package.json#L151) is a second change in a deletion PR, and that test may not be selected when only scripts/integration-progress-model.ts changes, so you can register it under the gate that owns integration-progress or explain why affected-selector owns it, or leave it as is.

The affected decision-kernel check failed only because two of eight mutant shards (kernel-errors and selectors-2) were cancelled, so it reported "Incomplete shard set: 6 report(s), expected 8". No test failed. I could not see why they were cancelled. selectors-2 does not touch this diff. For kernel-errors, the changes are a type-only alias and three removed tests whose hint assertions are still pinned per code, so I expect the same result. I did not run any tests myself.

There are no conflicts. Please rerun the two cancelled shards so the check gets all eight reports before merge.
