Luong NGUYEN 72d3b016e6 docs: sync all tutorials with latest Claude Code docs (April 2026) (#56)
* docs: sync all tutorials with latest Claude Code official docs (April 2026)

Update 44 documentation files to reflect the latest Claude Code features
from code.claude.com. Key content changes include new slash commands
(/ultraplan, /powerup, /sandbox), deprecated command removals (/pr-comments,
/vim), corrected skill description budget (1%/8K), new hook events
(PermissionDenied, InstructionsLoaded, ConfigChange), expanded Agent Teams
section, new plugin components (LSP, bin/, settings.json), and new CLI
flags (--bare, --tmux, --effort, --channels). Added "Last Updated: April
2026" metadata footer to all documentation files.

* fix(docs): correct env var values and alphabetical ordering

- CLAUDE_CODE_NEW_INIT=true → =1 in 02-memory and 09-advanced-features
- CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=true → =1 in 09-advanced-features
- Fix /powerup vs /plugin alphabetical order in slash commands table

* fix(docs): correct env var values in locale files (vi, zh)

Propagate CLAUDE_CODE_NEW_INIT=true → =1 and
CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=true → =1 corrections
to Vietnamese and Chinese translations.

# Expand Unit Tests
Expand existing unit tests adapted to project's testing framework:
1. **Analyze coverage**: Run coverage report to identify untested branches, edge cases, and low-coverage areas
2. **Identify gaps**: Review code for logical branches, error paths, boundary conditions, null/empty inputs
3. **Write tests** using project's framework:
- Jest/Vitest/Mocha (JavaScript/TypeScript)
- pytest/unittest (Python)
- Go testing/testify (Go)
- Rust test framework (Rust)
4. **Target specific scenarios**:
- Error handling and exceptions
- Boundary values (min/max, empty, null)
- Edge cases and corner cases
- State transitions and side effects
5. **Verify improvement**: Run coverage again, confirm measurable increase
Present new test code blocks only. Follow existing test patterns and naming conventions.
