Add style check-points to page contracts and enhance CLI options

[hungify]

This commit introduces the ability to define style check-points within page contracts, allowing for CSS selectors paired with Figma node IDs to be specified. The --style-check-selector and --style-check-node-id options have been added to the CLI for non-interactive contract creation. Additionally, the interactive prompt now supports adding multiple style check-points. The schema has been updated to reflect these changes, and tests have been added to ensure proper functionality and validation of style check-points in contracts.

📝 Walkthrough

Walkthrough

The CLI now supports optional page-level style checkpoints. Users can provide selector and Figma node pairs through flags or prompts. Contracts validate these checkpoints and may include expected styles fetched from Figma.

Changes

Page style-check contracts

Layer / File(s)	Summary
Style-check contract shape packages/contracts/src/contract.ts, packages/cli/src/contract/scaffold.ts	The contract schema validates selectors, Figma node IDs, optional expected styles, and nonempty page styleChecks arrays. CLI contract answers expose the optional checkpoint list.
CLI style-check collection and page wiring packages/cli/src/commands/contract.ts, packages/cli/src/contract.ts, .oxlintrc.json	The CLI accepts paired style-check flags, validates them, collects interactive checkpoints, fetches optional expected styles, rejects style-check flags for region contracts, and attaches checkpoints to page contracts.
Validation and authoring coverage packages/cli/tests/contract.test.ts, packages/cli/README.md	Tests cover flag, interactive, schema, omission, multiple-checkpoint, prompt-loop, and warning behavior. Documentation describes page-level styleChecks and JSON usage.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: ⚪ Minimal · up to 85ee3

The PR adds validated style checkpoints and related CLI options to page contracts without introducing an actionable merge-blocking risk; it is merge-ready after normal checks and review.

361-380: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Do not use --page-reason as the interactive-mode switch.

If a user supplies --page-reason but leaves other fields interactive, Lines 377-380 skip collectPageStyleChecks. The command then omits the page style-check prompt even though no style-check flags were supplied. This conflicts with the command behavior described in the README and the objective to support interactive check-points. Skip the loop only for a fully flag-driven invocation, or add an explicit non-interactive option. Update the test at packages/cli/tests/contract.test.ts Lines 467-494.

[greptile-apps]

Greptile Summary

This PR extends page contracts with element-level style checkpoints and adds CLI support for authoring them through flags or interactive prompts.

• Adds the validated styleChecks contract shape and exported checkpoint type.
• Adds paired CLI flags, interactive multi-checkpoint collection, and best-effort Figma style capture.
• Rejects page-only style flags for region contracts and adds contract/schema regression coverage.
• Documents page-level checkpoint authoring and contract structure.

Confidence Score: 4/5

The PR is not yet safe to merge because persisted page style checkpoints are still omitted from verification and therefore never execute.

Page contracts and the CLI now retain styleChecks, but the current page verification projection does not read or forward them, while runtime style comparison remains limited to the single selector-based path; the previously reported execution failure therefore remains blocking.

Important Files Changed

Filename	Overview
packages/contracts/src/contract.ts	Adds the validated page style-checkpoint schema and public type; the previously reported missing runtime consumer remains outstanding elsewhere in the verification flow.
packages/cli/src/contract.ts	Adds flag-driven and interactive checkpoint collection while correctly rejecting region-scope style flags and preserving mixed-mode prompting.
packages/cli/src/commands/contract.ts	Registers the paired style-check selector and Figma node CLI options.
packages/cli/src/contract/scaffold.ts	Extends page-scope scaffold answers to carry optional validated checkpoints.
packages/cli/tests/contract.test.ts	Covers schema acceptance, flag validation, mixed-mode prompting, and single or multiple interactive checkpoints.
