docs: sync upstream baseline to 393d397

[Jamkris]

Summary

Final PR of the 2026-05-13 upstream sync round. Advances the recorded baseline from e9c88458 (2026-05-11) to 393d397 (2026-05-12) — the upstream HEAD at triage time and the last commit evaluated this round.

Round 3 PRs

• #74 — triage / audit log (upstream/sync-rounds/2026-05-13.md)
• #75 — port: code-reviewer guardrails + prompt defense baselines

Of 67 commits in the focused range: 2 ported, 8 deferred (net-new feature additions: PRD command, network architect agents, motion skills, Quarkus, Django Celery, cost tracking, frontend design, homelab configs), 57 skipped with rationale.

Files updated (4)

• upstream/.upstream-sync.json — lastSyncedSha + lastSyncedAt + round notes pointing at the new audit log.
• upstream/README.md — baseline badge, Last-synced commit, date, round-notes pointer (now references both 2026-05-13 and 2026-05-12).
• upstream/ko-KR/README.md + upstream/zh-CN/README.md — mirrored.

Expected post-merge behaviour

• The validator passes — the prose SHA and JSON SHA agree on 393d397.
• Next scheduled or manually-dispatched upstream-drift workflow run will compute the delta against ECC's current HEAD. If ECC has moved past 393d397 (likely — they merge daily), issue #71 updates with the new (small) count. If no new ECC commits since 393d397, #71 auto-closes.

Test plan

• node scripts/ci/validate-upstream-sync.js — "OK — both files reference 393d397"
• npm run lint clean
• npm test 279/279
• Manual link check — README baseline → ECC commit, audit log links → 2026-05-13.md + 2026-05-12.md

Round end

This PR closes round 3.

Related to #71.

Walkthrough

Updated upstream synchronization metadata: .upstream-sync.json records a new evaluated commit SHA and "Round 3" sync-round outcomes; the baseline badge hash and sync-round file references are propagated across primary and localized README documentation.

Changes

Upstream sync metadata round 3 update

Layer / File(s)	Summary
Sync metadata source and primary documentation upstream/.upstream-sync.json, upstream/README.md	.upstream-sync.json updated with new lastSyncedSha and "Round 3 sync" notes; baseline badge SHA and "Round notes" link updated in primary README to reference the latest 2026-05-13 sync-round file.
Localized documentation updates upstream/ko-KR/README.md, upstream/zh-CN/README.md	Baseline badge hash and sync-round metadata references synchronized across Korean and Chinese localized README files to match the primary English documentation updates.
