* docs: sync to Claude Code v2.1.212
Bumps tutorial coverage from the v2.1.206 baseline (2026-07-11 sync) to
v2.1.212, plus a repo-internal accuracy audit that surfaced defects
independent of the version delta.
Fixed:
- Dead `#` memory-shortcut removed from 02-memory/README.md (two places
documented a discontinued quick-memory-add pattern as working, directly
contradicting the file's own commands table)
- Auto mode opt-in -> opt-out on Bedrock/Vertex/Foundry (v2.1.207)
- `auto` permission mode mislabeled "Research Preview" across
09-advanced-features/README.md, CATALOG.md, README.md, and the vi/ja/zh/uk
translations (auto mode is GA, gated only by plan/model/provider)
- `/fork` / `/branch` history corrected: they were a single aliased command
only from v2.1.77 to v2.1.161, not "renamed" as previously stated
- `effort` frontmatter enum in 04-subagents/README.md completed with `xhigh`
- Bundled-skills count reconciled in CATALOG.md (9 -> 10)
- INDEX.md Skills section count and Feature Coverage Matrix Total column
fully recomputed and reconciled (Skills: 22, Plugins: 39)
- Stale 2.1.160 footer cluster (5 files) bumped to 2.1.212
- QUICK_REFERENCE.md fully resynced (was 52 versions behind)
- 02-memory/README.md's Memory Hierarchy section rewritten: replaced a
fabricated 8-tier strict-precedence model with the verified structure
(CLAUDE.md files are concatenated into context, not overridden; 4 real
location tiers; rules and auto memory are separate mechanisms)
- 02-memory/README.md's Memory Architecture diagram no longer conflates
claude.ai's 24h synthesis cycle with Claude Code's continuous auto memory
- Import recursion depth corrected (was documented as 5, actually 4 hops)
Added:
- Subagent output scanning (v2.1.210) documented in 04-subagents/README.md
- Session-wide spawn caps (v2.1.212): WebSearch and subagent limits
- MCP long-running-tool auto-backgrounding (v2.1.212) in 05-mcp/README.md
- `claude auto-mode reset` and `/resume` picker (v2.1.212)
- Screen reader mode (v2.1.208): --ax-screen-reader / CLAUDE_AX_SCREEN_READER
- Task tool `mode` parameter deprecation note (v2.1.212)
Known gaps (deferred, not fixed this pass):
- 03-skills/blog-draft/ vs 03-skills/.claude/skills/blog-draft/: confirmed
the latter is gitignored local testing scratch, not a repo duplicate
* fix(INDEX): correct Skills row arithmetic and stale changelog notes
INDEX.md's Skills header/matrix shipped as 22 (5+9+8) despite the PR's
own CHANGELOG claiming it was fixed to 21 — three independent counts
(file-type breakdown, filesystem listing, changelog intent) agree on
21; the Docs column was off by one. Also removes two stale CHANGELOG
"Known gaps" entries this same PR already resolved (memory hierarchy
rewrite, blog-draft gitignore confirmation) and adds the missing
Fixed-section bullet documenting the memory hierarchy rewrite.
Add Chinese (Simplified) translations for all documentation, organized
under a dedicated zh/ directory that mirrors the English folder structure.

Translations originally contributed by @tanqingkuang in #45.
Restructured from *-CN.md suffix pattern into zh/ directory to prevent
the EPUB builder (scripts/build_epub.py collect_folder_files) from
picking up Chinese files via glob("*.md") inside module folders.
