Enable iOS device core parity and align docs/skills

[thymikee]

Summary

• enable iOS physical-device core command support in capability matrix and daemon handlers
• extend iOS runner transport for device destinations, signing/provisioning overrides, and tunnel-based command routing
• fix iOS device discovery to use devicectl --json-output and prefer hardware UDID
• enforce iOS device backend/feature constraints (ax, settings, simulator-only commands) with explicit errors
• add iOS physical-device integration coverage and runner/snapshot unit tests
• update README, website docs, and skill references to reflect final support matrix and setup guidance

Follow-up hardening

• enforce strict runner connection timeout budgeting across endpoint resolution, HTTP probes, and simulator fallback transport
• replace runner connect magic timing numbers with named, env-overridable constants
• guard AGENT_DEVICE_IOS_CLEAN_DERIVED=1 when AGENT_DEVICE_IOS_RUNNER_DERIVED_PATH is set (requires explicit AGENT_DEVICE_IOS_ALLOW_OVERRIDE_DERIVED_CLEAN=1)
• refactor runner client to reuse shared env truthy parser and deduplicate connection error construction

Validation

• pnpm typecheck
• pnpm test:unit
• pnpm test:smoke
• pnpm build:xcuitest
• IOS_UDID=00008150-001849640CF8401C AGENT_DEVICE_DAEMON_TIMEOUT_MS=240000 node --test --test-name-pattern "ios physical device core lifecycle" test/integration/ios.test.ts
