refactor(move): move daemon-shaped test helpers under src/daemon/__tests__/support
Summary
Daemon extraction PR 10b (test-kit, stacked on #3483): moves the four daemon-shaped test helpers — session-factories.ts, store-factory.ts, device-claim-store.ts, screen-recording-live-handle.ts, the helpers that import src/daemon/* types and stores — from src/__tests__/test-utils/ to src/daemon/__tests__/support/, so they travel with the daemon when PR 11 runs git mv src/daemon packages/daemon/src. Their root-helper imports were already rewritten to @agent-device/test-kit/* by the layer below; no other content change. Non-daemon importers (6 files: src/platform-runtime-gateway.test.ts, src/__tests__/lease-provider-profile-fields.test.ts, src/commands/cli-grammar/flag-declaration-admission.test.ts, and three provider-scenario files) import them from the support path for now; PR 11 turns that into a package fixture subpath. 228 files, all one-line specifier rewrites.
Validation
Tested at 483d3c0ba (this head). Serially on this exact commit: pnpm format + check:quick, pnpm check:layering, pnpm check:gate-manifest, pnpm check:fallow --base origin/main (clean on 539 changed files), pnpm check:affected --run (all runnable checks passed), plus eager-closure budgets / test-file-size ratchet. Unit-suite parity was measured on this identical tree (byte-for-byte): 1574 files both sides vs origin/main, zero tests lost, +34 additions all from #3483's new eager-closure entry assertions.
Risk: the 6 non-daemon importers now reach into the daemon test tree; tracked for PR 11's export, listed in the plan's residue report.
