chore(release): prepare 1.17.0

[XXPermanentXX]

Summary

• finalize the bilingual 1.17.0 changelog for native Managed Agent Deployments, CLI language switching, and Free Tier Auto-Stop fixes
• document the language configuration in the English and Chinese root/npm READMEs
• expose the language-switch command in the bailian-cli hub Skill while keeping generated command details in reference/config.md
• retain the already-synchronized 1.17.0 versions across all five packages and Bailian Skills

Verification

• vp check — 0 errors (5 existing warnings)
• vp test packages/runtime/tests/i18n.test.ts packages/commands/tests/config-ui.test.ts — 17 passed
• pnpm run sync:skill-assets — generated references and Skill versions are synchronized
• CI=true node tools/release/publish-channel.mjs --channel test --knowledge --dry-run — five-package build, pack, publint, and gitleaks checks passed
• root/package English and Chinese README copies match; git diff --check passed

Test note

A full vp test run was attempted. It entered live service-backed E2E suites and produced unrelated environment/service failures across knowledge, media generation, quota, and other integrations, then remained running and was stopped. The directly affected localization tests and the complete release dry-run passed.
