Luong NGUYEN 1e16914a8d docs: sync to Claude Code v2.1.257 (#180) 
* docs: sync to Claude Code v2.1.257

Audit against Claude Code v2.1.257 (repo baseline was v2.1.245, 12 releases
behind). Facts verified against the official docs and cross-checked against
the locally installed 2.1.257 binary.

Critical (P0):
- lesson-quiz L06 Q9 asked how many hook events exist, offering 16/25/31/40.
  With the real answer now 33, no option was correct. Option C 31 -> 33;
  answer letter unchanged.
- 03-skills taught SKILL.md `name`/`description` as required. Official docs
  now state all frontmatter fields are optional and `name` defaults to the
  directory name. Corrected in all five languages.

Hook events 31 -> 33 (PreModelSwitch/PostModelSwitch, v2.1.251) across 30
occurrences in 22 files, including three that read 25. Delta proved by
set-diff against the official event table: no phantom events. Both events
added to the 06-hooks tables with matcher, blocking behavior and 30s timeout,
plus detailed per-event sections.

CLI corrections verified against the binary:
- `claude plugin tag` takes a path, not a version
- `claude plugin init` / `validate` require their arguments
- `plugin init` scaffolds at ~/.claude/skills/<name>/, not project-local
- `--channels` entries must be tagged plugin:<name>@<marketplace>
- `--remote` is a deprecated alias for `--cloud`
- no `claude remote-control` subcommand exists, only the --remote-control flag

Also: CATALOG summary-table totals recomputed in all five languages (column 4
is a derived total, so the count change invalidated it); stale Opus 4.6/4.7
rosters aligned to canonical; self-assessment Advanced Features rescored 0-3
to stop a real gap being graded as mastery; 9 dangling quiz Review pointers
repaired; new features documented (--restricted, Fable 5.1,
experimental.cacheTtl, CLAUDE_CODE_SUBAGENT_MODEL_FORCE).

Deliberately out of scope: pre-existing translation staleness whose fix is
translation authorship rather than correction (ja/uk April-2026 root-doc
bodies, zh stubs, vi/README stub, translated CATALOG "New Features").

* fix(hooks): complete the 31 → 33 hook-event propagation across all languages

The v2.1.257 sync bumped the hook-event count in the lesson and catalog
summaries but left 14 files still asserting 31, four of which the same
commit restamped 2.1.257. It also bumped the prose count in
claude_concepts_guide.md without adding the two rows, making that file
contradict itself where it had been internally consistent before.

Adds PreModelSwitch and PostModelSwitch (v2.1.251) everywhere an
exhaustive enumeration exists, and corrects the count wherever a list is
deliberately partial:

- README.md / INDEX.md in en, ja, zh, uk and vi/INDEX.md — count 31 → 33
  and both events added to the lifecycle group
- resources.md in all five languages — count only; these lists end in
  "and more" and are partial by design
- claude_concepts_guide.md — the two missing table rows

Also brings every hook-event table up to the 33 its own summary row
claims. The English CATALOG.md listed 29; the translated catalogs listed
25 and the ja/uk concept guides 27 and 28. Completing them required
translating six events that had never reached the mirrors: Setup,
UserPromptExpansion, PermissionDenied, PostToolBatch, MessageDisplay and
DirectoryAdded.

Summary-table arithmetic is untouched — those columns count example
scripts, not events.

Verified: no stale count survives outside CHANGELOG history, every
exhaustive enumeration lists exactly 33, and pre-commit passes 23/23.

## 09. Advanced Features (4 files)
Advanced capabilities for complex workflows.
| File | Description | Features |
|------|-------------|----------|
| `README.md` | Complete guide | All advanced features documentation |
| `config-examples.json` | Configuration examples | 10+ use-case-specific configurations |
| `planning-mode-examples.md` | Planning examples | REST API, database migration, refactoring |
| `setup-auto-mode-permissions.py` | Seed `permissions.allow` for auto mode | Idempotent, `--dry-run` and opt-in flags |
| Dynamic Workflows | Deterministic multi-agent orchestration via `/workflows` (v2.1.154) | Comprehensive audits, migrations, scale-out |
| Scheduled Tasks | Recurring tasks with `/loop` and cron tools | Automated recurring workflows |
| Chrome Integration | Browser automation via headless Chromium | Web testing and scraping |
| Remote Control (expanded) | Connection methods, security, comparison table, device cards | Remote session management (no longer a research preview) |
| Cross-Session Messaging | `SendMessage` / `ListAgents`, including `notify_when_idle` (v2.1.236) | Coordinating sessions on the same machine |
| Keyboard Customization | Custom keybindings, chord support, contexts | Personalized shortcuts |
| Desktop App (expanded) | Connectors, launch.json, enterprise features | Desktop integration |
| | | |
**Advanced Features Covered**:
### Planning Mode
- Create detailed implementation plans
- Time estimates and risk assessment
- Systematic task breakdown
### Extended Thinking
- Deep reasoning for complex problems
- Architectural decision analysis
- Trade-off evaluation
### Background Tasks
- Long-running operations without blocking
- Parallel development workflows
- Task management and monitoring
### Dynamic Workflows (v2.1.154)
- Deterministic orchestration of tens-to-hundreds of background subagents
- Fan-out / pipeline / parallel stages for comprehensive coverage
- View runs with `/workflows`; `ultracode` `/effort` turns it on for a session
- Default size guideline is medium (aim for fewer than 15 agents) as of v2.1.219 — change it with **Dynamic workflow size** in `/config`
### Permission Modes
- **manual**: Ask for approval on risky actions (renamed from `default` in v2.1.200; `default` still accepted)
- **acceptEdits**: Auto-accept file edits, ask for others
- **plan**: Read-only analysis, no modifications
- **auto**: Everything, with background safety checks — a classifier reviews commands and protected-directory writes (configured via the `autoMode` settings object)
- **dontAsk**: Only pre-approved tools — auto-denies every call that would otherwise prompt. Claude runs only `permissions.allow` matches, read-only Bash commands, and calls approved by a `PreToolUse` hook
- **bypassPermissions**: Accept all (requires `--dangerously-skip-permissions`)
### Headless Mode (`claude -p`)
- CI/CD integration
- Automated task execution
- Batch processing
### Session Management
- Multiple work sessions
- Session switching and saving
- Session persistence
### Interactive Features
- Keyboard shortcuts
- Command history
- Tab completion
- Multi-line input
### Configuration
- Comprehensive settings management
- Environment-specific configs
- Per-project customization
### Scheduled Tasks
- Recurring tasks with `/loop` command
- Cron tools: CronCreate, CronList, CronDelete
- Automated recurring workflows
### Chrome Integration
- Browser automation via headless Chromium
- Web testing and scraping capabilities
- Page interaction and data extraction
### Remote Control (expanded)
- Connection methods and protocols
- Security considerations and best practices
- Comparison table of remote access options
- Out of research preview — a machine running `claude remote-control` appears as a device card in the Claude app's Code tab
### Cross-Session Messaging
- `SendMessage` between sessions on the same machine
- `notify_when_idle` — one opt-in notice when the other session next goes idle (v2.1.236)
- `ListAgents` reports the session's own name and lists live teammates (v2.1.239)
### Keyboard Customization
- Custom keybindings configuration
- Chord support for multi-key shortcuts
- Context-aware keybinding activation
### Desktop App (expanded)
- Connectors for IDE integration
- launch.json configuration
- Enterprise features and deployment
