feat(welcome): redesign sign-in page to match Figma card layout

[graycyrus]

Summary

• Redesign the Welcome/sign-in page to use the same white-card container layout as the Home page (centered card with rounded-2xl, shadow-soft, border)
• Add horizontal OAuth pill buttons (Google, GitHub, Twitter), "Or" divider, email input field, and "Continue with email" CTA — matching the Figma design
• Fix pre-push hook: scope rust:check to Tauri shell crate only, since the root crate's whisper-rs-sys cmake build fails on macOS (-mcpu=native unsupported by Apple clang)

Test plan

• Verify Welcome page renders with centered white card, logo, heading, OAuth buttons, divider, email input, and CTA
• Verify OAuth buttons (Google, GitHub, Twitter) trigger login flows correctly
• Verify email input accepts text and form submits
• Verify yarn rust:check passes (Tauri crate only)
• Verify pre-push hook passes on git push

Summary by CodeRabbit

• New Features

  • Redesigned welcome page with a new sign-in layout featuring OAuth login options and an email sign-in form.

• Chores

  • Optimized build script to streamline the Rust check process.

📝 Walkthrough

Walkthrough

Updated the rust:check script in app/package.json to invoke cargo check only for src-tauri/Cargo.toml instead of checking both that manifest and the root ../Cargo.toml. Refactored app/src/pages/Welcome.tsx to replace the TypewriterGreeting and OAuthLoginSection components with a new unified card-based sign-in interface featuring OAuth buttons, an email input field, and form submission handling.

Changes

Cohort / File(s)	Summary
Build Configuration app/package.json	Simplified the rust:check script to run cargo check against src-tauri/Cargo.toml only, removing the redundant check against the root ../Cargo.toml.
Welcome Page UI app/src/pages/Welcome.tsx	Replaced stacked TypewriterGreeting and OAuthLoginSection components with a new card-based layout. Added email state and handleEmailSubmit handler for email sign-in form. Renders filtered OAuth provider buttons (google, github, twitter) with compact styling, includes a visual divider, and email input field with submit button.

Poem

🐰 A script grows lean, one cargo less,
While Welcome's form puts users to the test,
OAuth buttons dance in a card so neat,
Email fields make the sign-in complete! ✨
