docs: sync to Claude Code v2.1.187 (#146)

* docs: sync to Claude Code v2.1.187

Sync the delta from v2.1.179 to v2.1.187 across six modules.

- slash-commands: reclassify `/review <pr>` as a supported PR-review entry
  point (same engine as `/code-review medium`, v2.1.186), no longer deprecated
- advanced-features: `!` bash output now auto-responds (v2.1.186);
  `/config key=value` shorthand + `--help` (v2.1.181/.183) and menu key
  behavior; built-in intent-based auto-mode blocks for destructive git/IaC
  commands (v2.1.183); `sandbox.credentials` / `sandbox.allowAppleEvents`
- subagents: `teammateMode: "iterm2"` display mode (v2.1.186)
- memory: `attribution.sessionUrl` setting (v2.1.183)
- mcp: `claude mcp login` / `claude mcp logout` CLI auth (v2.1.186)
- cli: `respondToBashCommands` setting; new env vars
  `CLAUDE_CLIENT_PRESENCE_FILE`, `CLAUDE_CODE_MAX_RETRIES` (cap 15),
  `CLAUDE_CODE_RETRY_WATCHDOG`, `CLAUDE_CODE_MCP_TOOL_IDLE_TIMEOUT`

Footers on all touched files bumped to v2.1.187.

* fix(advanced-features): correct respondToBashCommands version framing

The ! bash auto-response feature landed in v2.1.186 (confirmed against the
official changelog). The previous 'Since v2.1.187 (changed in v2.1.186)'
wording was misleading and inconsistent with 10-cli/README.md, which
correctly tags respondToBashCommands as v2.1.186.
