fix: scope runner diagnostics to sessions

[thymikee]

Summary

Route daemon request diagnostics into session request files and Apple runner/xcodebuild output into session-scoped runner logs, while keeping the shared daemon log for lifecycle and pre-session failures.

Expose runner/request log paths in open JSON and session inventory, and update help, docs, and AGENTS guidance for concurrent agents.

Touched 20 files; scope stayed within daemon request logging/session artifacts, Apple runner log append safety, client output types, tests, and docs.

Validation

• pnpm exec vitest run src/daemon/tests/request-execution-scope.test.ts src/daemon/tests/request-router-open.test.ts src/utils/tests/args.test.ts
• pnpm check:quick
• pnpm test:smoke (4 passed, 3 loopback-dependent cases skipped by environment)
• pnpm check:unit was rerun outside the sandbox; the full sweep had one runner-xctestrun timeout, and the focused rerun of src/platforms/ios/tests/runner-xctestrun.test.ts passed.
