refactor: split daemon client facade

[thymikee]

Summary

Refactors src/daemon-client.ts into a 181 LOC facade while preserving its public export surface and request orchestration behavior.

Architecture boundaries:

• lifecycle/settings and daemon reuse/startup live in src/daemon-client-lifecycle.ts
• daemon metadata lock/info parsing, stale cleanup, startup cleanup, and startup hints live in src/daemon-client-metadata.ts
• socket/HTTP transport selection, probing, fallback, and request mechanics live in src/daemon-client-transport.ts
• HTTP JSON-RPC/lease payload projection lives in src/daemon-client-rpc.ts
• request timeout aftermath, Apple runner cleanup, and daemon reset policy live in src/daemon-client-timeout.ts

Touched files: 7. The fallow health baseline only moves/reduces the existing daemon-client path allowance from the old file to the new focused modules.

Closes #727

Validation

Focused daemon-client unit coverage passed: pnpm exec vitest run --project unit src/utils/__tests__/daemon-client.test.ts src/utils/__tests__/daemon-client-lifecycle.test.ts src/__tests__/daemon-client-progress.test.ts.

Remote provider scenario command loaded successfully but both loopback-backed cases skipped in this environment: pnpm exec vitest run --project provider-integration test/integration/provider-scenarios/remote-daemon-client.test.ts.

Static/build gates passed: pnpm format, pnpm check:quick, pnpm check:fallow --base origin/main, and pnpm build.
