- Replace fictional `/think` example with official `ultrathink` keyword
- Fix Q4 options: `/think` → `/effort max`, `--thinking` → `ultrathink`
- Fix Q5: correct the answer that "ultrathink" DOES trigger deep reasoning
- Sync changes across English, Ukrainian, and Vietnamese translations
Background: `/think` is not a valid slash command in Claude Code (verified
against official commands reference at code.claude.com/docs/en/commands).
The correct way to trigger deep reasoning for a single response is to
include "ultrathink" in the prompt.
Sources:
- https://code.claude.com/docs/en/commands (no /think command exists)
- https://code.claude.com/docs/en/model-config (ultrathink is valid keyword)

Modules 06-hooks, 07-plugins, 09-advanced-features, 10-cli had
truncated translations (18-58% content loss). Retranslated from
scratch using original English sources.
All files now match expected ~40% size increase for Cyrillic.
