refactor(#2360): host dispatch table + state cutover pilot (ADR-2346 P1) (#2364)

* refactor(#2360): host dispatch table + state cutover pilot (ADR-2346 P1) Pilot cutover for ADR-2346 Phase 1 (epic #2345). Introduces the Layer-2 host dispatch table — dispatchHostCommand + HOST_COMMAND_ROUTERS, consulted in runCommand's default case after capability/overlay dispatch, before the unknown-command error. Migrates 'state' as the pilot: removes the hardcoded case 'state': arm; state now dispatches default -> dispatchHostCommand -> routeStateCommand, byte-identical to the old path (proven by the new state-command-cutover equivalence test, 5-category template). Host commands are NOT capabilities (core, non-toggleable, no tier/activationKey) — the capability registry stays reserved for toggleable feature bundles per ADR-959. This is the host-vs-capability distinction the merged ADR-2346 lacked; the ADR is corrected here alongside the code that realizes it. - gsd-core/bin/gsd-tools.cjs: HOST_COMMAND_ROUTERS + dispatchHostCommand (prototype-pollution-safe); wired into default case; case 'state': removed; dispatchHostCommand + HOST_COMMAND_ROUTERS exported for tests. - tests/state-command-cutover.test.cjs: UNIT/DISPATCH/BEHAVIOR/REGISTRY equivalence (recording-mock + runGsdTools end-to-end + pollution guard). - docs/adr/2346-*.md: refine Decision 1/2 to the host-table vs capability- registry model (correction that did not land in the merged #2355). Behavior-preserving. Subsequent P1b/c PRs migrate phase/init/roadmap/validate/ verify using this proven template. Closes #2360. * test(#2360): regenerate golden fixtures + allowlist for state cutover Bookkeeping for the gsd-tools.cjs change: npm run gen:golden regenerates the install-parity fixtures (gsd-tools.cjs content hash changed), and the new tests/state-command-cutover.test.cjs is added to the lint-test-file-count allowlist under the 'state' prefix. * refactor(#2360): migrate remaining Tier-1 routers (phase/init/roadmap/validate/verify) Completes P1: all 6 Tier-1 host routers now dispatch via HOST_COMMAND_ROUTERS (state landed in the pilot commit). init preserves its #1688 warnIfStaleBake pre-hook; validate binds the output emitter. Cutover test extended to assert all 6 are consumed + owned. Golden install-parity fixtures regenerated.
