* docs: sync to Claude Code v2.1.156 and Claude Opus 4.8
Model bump Opus 4.7 -> Opus 4.8 and version sync v2.1.150 -> v2.1.156.
- Rewrite effort-ladder claims for Opus 4.8 (default `high`; `xhigh` on
4.8/4.7; `max` on 4.8/4.7/4.6 and Sonnet 4.6; Haiku has no effort).
- Replace soon-removed CLAUDE_CODE_OPUS_4_6_FAST_MODE_OVERRIDE with the
`/model claude-opus-4-6[1m]` + `/fast on` path; note Opus 4.8 fast mode.
- Bump lineup tables to Opus 4.8; fix Haiku 4.5 context (1M -> 200K).
- Sweep Compatible Models + version/date footers to 2.1.156 / May 29, 2026
across 23 English docs (incl. 2.1.138/2.1.145 stragglers).
- Re-document `/simplify` as a distinct cleanup-only command (v2.1.154).
- Add Dynamic Workflows + `/workflows`, MessageDisplay hook (count 29->30),
disallowed-tools frontmatter, `/reload-skills` + SessionStart outputs,
`/model` default-save inversion, lean system prompt, status-line
COLUMNS/LINES, and the ultracode `/effort` note.
* docs(cli): drop unverified fast-mode dollar pricing, keep verified rate/speed multipliers
Sync covers v2.1.128, v2.1.129, and v2.1.131 (May 2026). Highlights:
gateway /v1/models discovery is now opt-in (CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY),
added --plugin-url flag, disableRemoteControl setting, /mcp tool-count display,
expanded skillOverrides values, /context viz no longer leaks into conversation,
Ctrl+R cross-project default. Also reconciles slash-command count to 60+ and
fixes the skill-count entry in CATALOG.
Update all documentation footers from generic "April 2026 / 2.1+" to
the specific sync date (April 9, 2026) and documented version (2.3.0).
Also add version/date footers to zh/CATALOG.md and
zh/01-slash-commands/README.md which were missing them.
