fix(workspaces): repair Grok Web startup and preserve diagnostics

[luokerenx4]

Opening Grok in Web exited before the ACP handshake because --no-leader was passed to the pager TUI instead of the agent subcommand. Compose grok agent --no-leader … stdio, with runtime model/effort flags scoped to the agent and top-level rules kept before it.

Preserve the actual child exit diagnostic when transport disposal rejects startup, and leave failed-open registry rollback to the route to avoid racing its temporary-file replacement. Ignore live ACP user-message echoes while continuing to replay user history on resume; real Grok echoed the prompt and previously rendered it twice.

Verification:

• Reproduced the exact rejected argv against installed Grok 1.0.13; corrected argv completed a real ACP initialize handshake with loadSession support.
• In the independent UI Setup project, opened the user's existing Grok Session, received a real “连接正常” reply, reopened the same Session and verified its history, then received “收到” with no duplicated prompt. Both prompts explicitly prohibited tool use and file changes.
• pnpm test:changed: 21 files, 473 passed.
• pnpm test:owner:runtime-cli: 169 files, 1716 passed, 1 skipped.
• Root npx tsc --noEmit passed. No UI source or Electron-specific launch contract changed.
• Previous PR fix(workspaces): preserve resumed sessions and support text answers #1391 checks and its post-merge installer smoke passed.

This validates Grok text turns and Web history restoration. It does not claim tool-approval or all-runtime credentialed acceptance from the broader Web surface plan.
