docs: sync to Claude Code v2.1.233 (#168)

* docs: sync to Claude Code v2.1.233

Bring the tutorial from the v2.1.220 baseline up to v2.1.233 (13 releases)
per update-plan-2026-08-15.md.

Corrections:
- Remove /ultraplan (removed in v2.1.222); point at plan mode instead
- Drop the 200-subagent-per-session cap and CLAUDE_CODE_MAX_SUBAGENTS_PER_SESSION
  (cap removed in v2.1.224)
- Note TaskCompleted/TaskCreated only fire when todo tools are enabled

Updates:
- /review documented as an alias of /code-review (v2.1.223)
- fork subagents default to interactive (v2.1.232)
- ultrareview v2.1.227 floor, --post/--no-post
- GitLab MR support for -w/--worktree and Agent View

New sections:
- Cross-session messaging (ListAgents, SendMessage, crossSessionInbound)
- Sandbox credential masking (v2.1.221, v2.1.224)
- Trust and permission scoping
- archive and command plugin sources, conditional plugin activation
- claude self-hosted-runner, 7 new env vars

Translations (vi/ja/zh/uk) mirrored where the corresponding pages exist.
Every modified file carries the 2.1.233 metadata footer; files already at
2.1.220 with no content change were left alone.

* docs: address review findings from the v2.1.233 sync

- Mirror the /review alias correction (v2.1.223) into vi/ja/uk/zh
  01-slash-commands: add the live alias row, drop the stale row from the
  deprecated table, and rewrite the history bullet. All four still called
  /review deprecated in favour of a code-review plugin while carrying a
  2.1.233 stamp.
- Rewrite the 10-cli CLAUDE_CODE_FORK_SUBAGENT row to agree with
  04-subagents: fork mode is on by default in interactive sessions on every
  build since v2.1.232; the variable enables it where it is off by default.
- Remove a stray blank line that split the 10-cli environment-variable
  table, leaving the seven new v2.1.221-v2.1.233 rows without a delimiter
  row and rendering them as literal pipe text.
- Add the todo-tools caveat to the TaskCompleted row alongside TaskCreated
  in claude_concepts_guide, uk/ja concepts guides, and the uk/vi/zh/ja
  CATALOGs.
- Fix the ja 07-plugins and 09-advanced-features footers, which paired a
  2.1.233 version stamp with an April 24 last-updated date.

* docs(subagents): correct the stale fork-subagent claim in ja pages (#171)

ja/10-cli and ja/04-subagents both stated that CLAUDE_CODE_FORK_SUBAGENT
only enables forked subagents on external builds (Bedrock, Vertex,
Foundry) with no effect on the Anthropic API. That was true at v2.1.117
but has been wrong since v2.1.232: fork mode is on by default in
interactive sessions on every build, first-party or not, and the variable
now turns it on where it is off by default (claude -p, the Agent SDK, or
Claude Code older than v2.1.232).

Both pages remain stamped 2.1.119 on purpose. Only the individual claim
was verified and corrected; bumping the page stamp would assert a
whole-page verification that has not been done. Do not bump these stamps
without a full resync of the pages.
