* 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

**Session-scoped outputs (v2.1.152):** A `SessionStart` hook can return JSON to re-scan skills and set the session title:
```json
{
"reloadSkills": true,
"hookSpecificOutput": {
"sessionTitle": "Payments migration"
}
}
```
Top-level `reloadSkills: true` triggers a skill re-scan in the same session (the same action as the `/reload-skills` command), making skills the hook just installed available immediately. `hookSpecificOutput.sessionTitle` sets the session's display title on startup and resume.
### SessionEnd
Runs when session ends to perform cleanup or final logging. Cannot block termination.

### Security Notes
- **Workspace trust required:** The `statusLine` and `fileSuggestion` hook output commands now require workspace trust acceptance before they take effect.
- **Status-line terminal size (v2.1.153):** Status-line command scripts now receive `COLUMNS` and `LINES` environment variables, so a script can adapt its output to the terminal width/height (e.g. `[ "$COLUMNS" -lt 80 ] && short_output`).
- **HTTP hooks and environment variables:** HTTP hooks require an explicit `allowedEnvVars` list to use environment variable interpolation in URLs. This prevents accidental leakage of sensitive environment variables to remote endpoints.
- **Managed settings hierarchy:** The `disableAllHooks` setting now respects the managed settings hierarchy, meaning organization-level settings can enforce hook disablement that individual users cannot override.
- **PowerShell auto-approve (v2.1.119):** PowerShell tool commands can be auto-approved in permission mode, matching Bash. This brings parity for Windows users running Claude Code with PowerShell-backed shell tools.
