docs: cover browser controls in CLI contract

[BlueRaddish]

Summary

The CLI migration contract now covers shipped browser controls for React grab, DevTools, focus and design modes, zoom, history clearing, and console/error lists. Eight no-socket help probes pin their public command forms so later help changes are visible to the contract test.

Fixes #15707.

Testing

• python -X utf8 scripts/check-cli-contract-verbs.py passed: 219 dispatched verbs covered.
• tests/test_cli_contract_help.py parsed all 235 probes; the eight new browser help needles matched the current CLI help source. Executable probes require a built macOS CLI and were not run locally.
• python -X utf8 scripts/localize_changes.py passed: no changed translation keys and zero catalog parity errors.
• python -X utf8 scripts/verify-local.py passed its selected feature-flag policy check; Swift syntax was skipped because no Swift files changed.
• git diff origin/main..HEAD --check passed.

Prepared with AI assistance.

Summary by cubic

Documents shipped browser control commands in the CLI migration contract, closing #15707.

• Adds contract rows for React grab, DevTools, focus mode, design mode, zoom, forced history clearing, and the split console/error list and clear forms.
• Pins eight no-socket help probes via cmux help browser (not browser --help, which prints only the short usage) so future help output changes are caught by the contract test.

^{Written for commit d9e78db. Summary will update on new commits.}

Summary by CodeRabbit

• Documentation
  • Updated CLI guidance for browser inspection and control commands, including React-grab, DevTools, focus and design modes, zoom, and forced history clearing.
  • Clarified that console and error inspection use separate list and clear subcommands for a selected surface, replacing the combined browser command forms.
  • Added no-socket help probes for browser commands, including the console and error subcommands.

📝 Walkthrough

Walkthrough

The browser CLI contract documents browser control commands, separates console and error list and clear commands, and adds no-socket help probes for these commands.

Changes

Browser CLI contract

Layer / File(s)	Summary
Browser command contract docs/cli-contract.md	Documents React-grab, DevTools, focus-mode, design-mode, zoom, and history-clear commands. Separates console and error list and clear commands. Adds no-socket help probes for the commands.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~4 minutes

Change: Other · Severity of issue fixed: Low

Suggested reviewers: austinywang

Merge Risk: ⚪ Minimal · up to d9e78

Review details

Systems and components

• observed — docs (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in docs/cli-contract.md: The browser command contract adds React-grab toggling with an optional terminal return target; DevTools toggle/console; focus-mode enter/exit/toggle; design-mode enable/disable/toggle/status; zoom in/out/reset or a numeric factor; and forced browser-history clearing, with --yes also accepted as confirmation.
• observed — Modified behavior in docs/cli-contract.md: The prior combined browser console and browser errors entries are replaced by separate browser console list|clear and browser errors list|clear commands, scoped to the selected surface.
• observed — Modified behavior in docs/cli-contract.md: No-socket browser help probes are added for the new React-grab, DevTools, focus-mode, design-mode, zoom, and history-clear commands, and for the console <list|clear> and errors <list|clear> forms.

CI fast guards failed on d9e78dbfea (https://github.com/manaflow-ai/cmux/actions/runs/37152132445). It does not block the merge; a red guard merged into main breaks it for every open PR.

Validate owned Mac build state (red on main too, not this PR)

Main has failed this step since #17168 by @teamleaderleo (self-merged) (#17169). Merge main again once the fix lands there.

Agents: python3 scripts/ci/guard_attribution.py fix applies the mechanical fixes locally. This comment is updated in place on each push.
